ATI display driver rollback

I have desktop running Enterprise Linux server 2.6.18-164. Recently I installed ATI display driver on it. After that I am not able to restart my machine. Is there any way to roll back the recent driver changes???

You can try to boot in text mode (no graphics) and check /etc/X11 directory. Usually, whenever a change in graphics settings occurs, the system makes a backup of the original configuration file (xorg.conf) and then applies the new settings. So, you can try to replace the current configuration file (xorg.conf) with the old one (xorg.conf.backup), if it exists...

  • ATI Display Driver

    I am trying to install the the ATI Display Driver package for a T500 without any of the applications that are included with it. In other words, I only want to install the drivers and nothing else like the Catalyst Control Center, etc.
    When I try to do a customized install,  I cannot uncheck any of the boxes I don't want installed. It seems like it is all or nothing. what's customizable about that?
    Is there a way to do what I want?
    Thanks

    You could ignore the fact that catalyst control center is installed and just remove CCC from startup (under HKLM\.....\Run in registry) when Windows is starting. Or you could uncompress the package and just install the driver by going into device manager and choose to update driver the driver then select the directory where you uncompressed the package.

  • ATI display driver fails to work with new kernel

    Hi,
    I've just upgraded from
    OEL kernel-2.6.18-194.11.3.0.1.el5.x86_64
    to most current
    OEL kernel-2.6.18-194.11.4.0.1.el5.x86_64
    and got the problem with ATI display driver. Whenever I perform kernel upgrade, I have to recompile vendor-provided ATI display driver downloadable from AMD/ATI site, because system ATI driver, provided by OEL/RHEL as kernel module, doesn't work properly (too slow). I did that hundred times and never had a problem. This time the problem is that after upgrading to new kernel and recompiling the existing ATI display driver (Revision 10.8), it doesn't work anymore, even though it worked perfectly with previous kernel. I cannot even start X11 (glibc problem reported with stack traces!!!). The newest ATI display driver (Revision 10.9) "works" with new kernel, but display is awfully slow making any serious work impossible. It is even slower than system-provided ATI driver.
    I am pretty sure the problem is in new kernel. As I have no backup of old kernel files and couldn't download the previous OEL kernel files from ULN, neither binary nor source (the files do not exist on ULN anymore, only the recent kernel files), I downloaded the previous kernel source from ftp.redhat.com, compiled the kernel and downgraded to it, recompiled ATI display driver, and everything works properly and fast as before upgrading. I can remember that ULN site used to have all kernel versions prior to actual one and cannot understand why Oracle dropped this practice. As I have an ULN account, I certainly want to have OEL patched kernel.
    My question is: does anybody know how and where I can download the previous OEL kernel-2.6.18-194.11.3.0.1.el5.x86_64 binary rpm files or at least source rpm file?
    Maybe Sergio or Tommy can help?
    Thanks in advance.

    I have experienced the same with Ubuntu some years ago - specific feature (hack?) that was implemented in the kernel was deprecated. This was used by the display driver for an onboard Intel graphics chipset. Beryl (which was subsequently merged with Compiz) turned into a horribly slow experience. As far as I recall, a subsequent kernel patch "fixed" things as a number of users were affected, of which many complained very loudly.
    Anyway, I think the lesson here is that OEL is not really the correct distro to use for a desktop. A broken ATI driver for the OEL kernel? Does not really feature in the scheme of things for OEL support. Oracle Grid/RAC/Enterprise/Standard Edition do not care. Oracle's application servers (Apache, Weblogic, etc) do not care. Etc.
    Sure, GUI desktop access to an OEL server is needed (like when running dbca or an installer) - but that can easily and effectively be done using vncserver for example and running twm.
    You may be able to fix/work-around the problem with the current kernel update.. you may be able to roll back the update. But what about the next time when some other component does not work after a patch or an update? Surely it is a lot less stressful and frustrating to rather use a desktop distro, like Ubuntu, instead?

  • Monitor Is Flickering - ATI Display Driver Problem Error Message

    Hello, for the last few weeks, I have been having a monitor issue. Everytime I turn my computer and monitor on, it is flickering like crazy on my HP 2509B Desktop Monitor, and on the right bottom corner a flag shows up with ATI Display driver, and I am trying to figure out how to repair this monitor issue. I don't know if it is coming from the Monitor itself or its coming from the Mother Board TOWER, I am going crazy with this and its hurting my eyes everytime I turn it.
    Sometimes the flickering would just go off by itself, and now its doing it constantly. I don't know what to do with this.
    I love my monitor and I hate to see to replace it or something. Please help me with this. I hope it is not a driver hardware issue.
    I would greatly appreciate all the help I can get to do this myself if not then I am going to have to take to the store I bought it from and get them to help me out, but I want to do this on my own. If you can help. Thanks

    if you have another monitor you can test it to see if if does the same thing and also check the cable and maybe use a different one to see if the cable is not the cause which i doubt
    Please provide Kudos to whom has provided answers or
    good points or advice..

  • [W500 and Windows 7] ati display driver stopped responding and has recovered

    Hi,
    I installed Windows 7 64bit on my W500 (almost 3 weeks old). It installed a driver for the ATI display card from Windows Update. However, since yesterday, I regularly get a driver crash (I assume...).
    It's happening when I'm scrolling in a webpage, suddenly the page hangs, the mouse and Windows itself hangs seconds later and after that, after 5 seconds, my screen goes black, the machine beeps and it's back. In the tray, I get an error: ati display driver stopped responding and has recovered.
    In the details of the driver, the following can be seen:
    Driver Date: 28/04/2009
    Driver Version: 8.612.0.0
    The card is recognized as a 3650.
    Am I doing something wrong here? Can I test with another driver (I tried installing the Windows Vista 64bit, but it doesn't seem to be willing to install...)?
    Thanks in advance,
    gill

    I have the exact same hardware and software (Win7 64) and I'm getting precisely the same symptoms, screen blanks out when I am scrolling a web page vertically using the trackpoint and the center blue trackpoint scroll button. 
    It's really annoying.
    It also never happens when the laptop is in the dock, or when the integrated graphics are engaged, this only happens when the ATI chip is running and only since ATI released the new Windows 7 drivers.
    Previously I'd ran this box on on Win7 64 but used the Vista 64 bit graphics drivers from ATI and didn't have the problem, but installation was a pain.

  • Equium A300D - Toshiba ATI display driver upgrade is not working

    Hi
    Has anybody else found the Equium A300D PSAK2E Windows Vista 32 bit Toshiba ATI display driver download will not work from the download centre? If you choose run, the download causes the windows explorer to crash during the install and the upgrade fails, the same with save and the install does not self install.
    I have been trying to get the TV out S-Video port working. See thread on TV out not working. I have tried everything. has anybody else got this problem as Toshiba are unaware of any problems with the S Video TV out not working on this machine.
    Thanks Vince

    Hi,
    The down load downloads ok but when you try and unzip it, then install it halfay through you get an error message stating windows explorer has stopped working and it has crashed. The Graphic card then will not work. I have tried uninstalling all the ATI software and deleting the left over files but it still wont install.
    I have downloaded the programme from the ATI site and this installed ok and the graphic card is working. The s video tv port still will not work.
    I have gone into great detail on the post regarding the TV out not working about what i have done. When the s video lead is connected the computer can see the tv but will not output, when you try and enable the display the display will not enable. I have used the FN f5 key with no success, changed settings on the avi controller and display settings in the control panel
    I will take the machine back to where i bought it from next week and see if they can get it to work!

  • Satellite Pro A60: ATI display driver keeps breaking down

    I have had my Sat pro A60 Laptop for about a year now.
    I have had a few problems with it since I got it but the main problem has just occured within the last 6-7 months.
    The ATI display driver keeps on breaking down and in order for it to work I have to restart the system. This has been an ongoing problem for quite some time and it's now getting rather irriating. It does it at the most inconvenient times like when I am watching a DVD or listening to a CD.
    Sometimes when I put the computer on standby, the display doesn't even start up again and the screen remains blank. In order to sort this out I have to switch off the laptop and then restart it. The main problem I have put this down to is overheating as it can get quite hot when I use it.
    I sort of know how to sort this problem out, just by clearing dust from the fans. But if there is any other solution to this please help.
    Thanks!

    Hi
    Mostly the overheating happens because of the dirt and dust inside of the cooling modules. The fans cannot work properly and cannot spin with full performance.
    I think you should check the fans. I think the easiest way to clean the fans is to use the vacuum cleaner hose against the fan grilles.
    About the display issue: In your case I would recommend firstly to update the display driver. Additional if the OS runs since a long time on the notebook so maybe a new OS installation form the Toshiba recovery CD would help.

  • ATI display driver lost with Linux and XP dual boot os

    I brought ThinkPad W500 with windows vista. I want to get rid of the hidden boot system reserved partition and downgrade to windows xp and install OpenSuse os. Following some sourses found on the web, I first set the bios sata ahci mode to compatable mode. Then install windows xp and update the sata driver. Restart and reset the bios sata back to ahci mode. It works fine with windows xp and I install back all driver. Finally I install OpenSuse and create dual boot with Grub. 
    But a serious problem come up with me. Everytime after restart from the linux os and back to windows xp, xp doesn't regonize the ATI display divice and tell me no driver installed with low screen resolution. And I have to restart the machine and boot direct into xp for the second time and the problem gone. But it is so annoying of doing this everytime. Anyone can help? Many thanks.
    Solved!
    Go to Solution.

    Hi stanleyimko,
    I don't have an answer, just a couple of questions:
    Does your W500 have switchable graphics?  If so, you may have to turn off "let the OS detect" or permanently select one or the other in BIOS.  XP isn't switchable aware, so I don't know why that would make a difference.
    Do you see the problem on cold (re) boot to XP, or only on warm reboot from Linux to XP?
    Seems like something is leaving your BIOS in an odd state (I guess that's obvious) and maybe a cold reboot would sort it.

  • Satelite Pro A200 ATI display driver problem

    Hello there,
    Have following problem: Can't install ATI software on my notebook. There is an error message during installation: "Catalyst Install Manager can't initialize Detection Manager".
    OS - Vista Business
    Display adapter - Mobility Radeon HD2600
    Any suggestions?

    Hi
    You could try to use another installation procedure;
    - Unzip the ATI graphic card driver package
    - access the device manager and choose the graphic card
    - choose update the driver and point to the palace where the display driver package was unzipped.
    This should help to renew and to reinstall the graphic driver.

  • Satellite L850-1HT - Windows 7 ATI display driver - where to find?

    Hello,
    I've got a L850-1HT (PSKG8E) , I installed a fresh Win7 64bit, but I can't find any drivers that would work with my laptop version.
    In the Toshiba drivers area for win7 iIcan only find drivers suitable for Intel graphics, no AMD drivers.
    Can anyone help me here.
    Thank you.
    Message was edited by: deaconpt

    Hi
    Take a look into the drivers download area of Satellite L850 PSKDLE series.
    There you can find the ATI / AMD display driver and these both series use the same graphic chip therefore this driver should work for PSKG8E series too.

  • Satellite Pro A100 PSAACE: cannot install ATI display driver

    Hi all,
    I have experienced a series of problems with my Mobility Radeon X1400 graphics card that I'm sure could be resolved by downloading the latest drivers. This I have to do from the Toshiba website as the ATI website offers no support for it. But I have experienced multiple problems downloading the file archive.
    It always says that there is an error: "Header error... (missing or corrupt)" and it asks me to redownload the file, I've done this three times now with the same results, I'm starting to get a little frustrated- can somebody +please help+. I have noticed that the downloaded (and useless) file is smaller (by over 50%) than the intended size-- I don't know if that helps at all...
    Pre-emptive thanks if you can help me with this problem.

    Hi
    What to say I have noticed that the drivers download server is very slow. Looks like an overload possibly all the packages would not transmitted correctly and therefore this error message appears.
    I know that this could be very frustrating and I really understand you because I have tried to download other driver and the performance is really slowly but I dont see any other solution as trying to download the graphic driver package again
    Good luck buddy

  • ATI Radeon 5470 Corrupted Display Driver

    Hi, I've updated to windows 8.1 and I'm trying to install the old ATI Mobility Radeon HD 5470 Display Drivers, but when I go to AMD website it tells me to download a new version, and after I install that version I get like 10 fps at Counter Strike: Global Offensive, I think that before I updated to Windows 8.1 I had the ATI Mobility Radeon HD 5470 Display Driver, but it got corrupted so I had to download the new one, but I want to use the old version because atleast it was stable and I could run the game smoothly. Is there anyway I can download the ATI display driver that comes with the computer? Since mine got corrupted and I need to replace it. I don't even know how to keep windows from installing the corrupt one..
    Please help

  • R400/T400/T500/W500: display driver "amdkmdap" crashes

    Executive summary: All current Lenovo ThinkPads with switchable graphics (R400, T400, T500, and W500) have usability issues in connection with Vista and the use of external monitors. For more than half a year, users were plagued by frequent Windows crashes. During that time frame, Lenovo did not comment on the various available reports and complaints. By the end of April 2009, Lenovo resolved many issues by releasing a new official driver. Though several problems, including severe ones, remain as of today. Lenovo has said to be actively working on the remaining issues (without outcomes so far).
    Important information for affected users: If you're having one of the issues reported here, then Lenovo advises you to call your local Lenovo Support. Demand that a case is submitted to hardware engineering. In particular, you should ask for "a CMVC case to be created and escalated". Using these "code words" ensures that your case is properly addressed.
    Old problem description
    On Vista 32 and Vista 64, the ATI display driver "amdkmdap" crashes when an external monitor was active before OR an application (game) using DirectX technology is used. The user typically receives a couple of so-called "Timeout Detection and Recovery" (TDR) messages from Vista:
    (Click here for an explanation of the message from Microsoft)
    Sometimes, amdkmdap crashes several times in a row. Then Windows crashes with a so-called "BSOD", likely resulting in data loss. Typically, Windows detects "atikmpag.sys" as the crashing driver. Sometimes, also an instantaneous reboot happens independent of prior TDR crashes. In such a case, no BSOD is displayed.
    The following movie illustrates the phenomenon: http://www.youtube.com/watch?v=LBX9QsCmrpY
    This behavior above has been confirmed for the following ThinkPad models: R400, T400, T500, and W500 (see below). Problem reports indicate that the symptoms are often related to playing games and/or the notebook being docked and the external monitor being connected via DVI.
    Though, the presence of these two conditions is not necessary to trigger the driver crash:
    There are reports where no dock was involved and the external monitor was connected directly to the notebook's VGA port.
    Furthermore, there are reports where the notebook was docked and an external monitor was connected to the DVI port.
    So far, there has been no report relating to a monitor being connected to the Display Port which is available on some models. (Possibly because this port is not used.)
    There are a few reports where neither a dock nor an external monitor was involved.
    Playing certain games reliably triggers the crash.
    Steps to reproduce
    While intially (around September 2008 - October 2008) the crash could be triggered easily, the situation is now (December 2008) more complex. The crashes do still occur, though there is no clear pattern anymore. According to various reports, the display driver crash can be triggered as follows:
    Resuming from standby
    Watching a DVD.
    Playing one of these games: Fallout 3, Bioshock, Team Fortress 2, Knights of the Old Republic.
    Arbitrarily during normal work. On a normal working day, the problem occurs at least once.
    Further issues
    Here are more issues which seem to be related. More information can be found in other posts of this thread:
    The notebook display and/or the external monitor runs at a low resolution after resuming from standby.
    After the login both monitors flicker while adjusting the resolution of the monitor.
    The external monitors cannot be activated using Presentation Director.
    The external monitor is blank after docking or undocking.
    There are some reports about display driver crashes on machines running Windows XP.
    The switchable graphics drivers limit the useable RAM under Vista 32 to 2.5GB (i.e. 500MB-1GB less than usual).
    Workarounds
    Lenovo has released a new "tip" document which provides a link to a new driver. Get it here but be sure to read the instructions!
    (Old tips follow below the line. Consider them as obsolete.)
    Here are some tips which might make the problem occur less often. I have not tried all of them. Though, A. and B. have improved the situation for me; your mileage may vary.
    A. If you do not have to use an external monitor, then switch to Intel graphics for time being.
    Otherwise:
    B. Make some changes to your system:
    Disable Aero.
    Create a new profile in the power manager with the following setting: When running on AC, turn off the monitor after 40 minutes. (Thereby, the notebook goes less often to standby.)
    Install the newest graphics drivers.
    Install the newest BIOS.
    Install the newest Hotkey utility.
    Install the newest drivers.
    C. Disable the switchable graphics in the BIOS setup and install modded drivers from ATI (see zilla's post in this thread for instructions).
    The last workaround (C.) has been confirmed to work reliably by several users. Though, thereby you use drivers which have not been tested by Lenovo. It's possible (but not very likely) that damage results by doing so. Also, it might be difficult to install a future Lenovo driver which resolves the issues reported here. Finally, you cannot use the power-saving Intel graphics. Thus, you should only use this workaround if you know what you are doing.
    The programs can be downloaded from the following locations. Notice that System Update does not always offer you immediately the lastest versions.

    "ThinkPads are supposed to be good, so you'd think there wouldn't be a problem like this."
    "honestly it is completely unacceptable for lenovo to have done nothing this long. I paid extra to get the ATI card, and now I can't hook up my laptop to an external monitor without it crashing. I will probably end up selling the laptop soon since using an external monitor is extremely important to me and lenovo doesn't seem to care about fixing the situation."
    Update:
    - Lenovo support has informed me today (2008-10-24) that they are working on the problem.- changed subject (was: Major troubles with DVI-port and a T400) to reflect new information.- changed message body to reflect new information

    Original post
    Hi there!
    I have major troubles using a Dell 2709W monitor with my T400. 
    The notebook is attached to a Advanced Mini Dock to which the monitor is connected via DVI.
     The problems are as follows.
    A. Activating the external monitor often fails
    Steps to reproduce:
    1. Attach a Dell 2709W via DVI to an Advanced Mini Dock which is connected to a T40
    2. Start Windows and make sure that the T400 is running on the ATI card.
    => Dell monitor enters power saving mode because no signal is coming.
    3. In Windows use either the Presentation Director, Windows, or the ATI tools to activate the Dell monitor.
    Expected result: The Dell monitor is activated and the Windows desktop is shown on it.
    Actual result: It takes 1-3 seconds for the Dell monitor to display something. The monitor shows the Windows desktop for a short period. Then it's black again and the monitor returns to the power saving mode .
    Analysis: It seems that the Presentation Director, Windows, or the ATI tools (or more aptly, I guess, the ATI driver) expect a quick response from the DVI-port that a monitor is present. If they do not receive the response, the DVI-port is deactivated again. Since the monitor is too slow to respond and enters the power saving mode too quickly, the monitor can hardly ever be activated.
    Suggested change: Change these tools (or the ATI driver) so that they wait longer for a response on the DVI-port.
    B. Resuming from monitor sleep causes Windows to fall back to a low resolution if the Dell monitor was activated before
    Steps to reproduce:
    1. Attach a Dell 2709W via DVI to an Advanced Mini Dock which is connected to a T400
    2. Start Windows and make sure that the T400 is running on the ATI card.
    3. Select the Energy Star profile
    4. Activate the Dell monitor
    5. Don't use Windows until the notebook display and the Dell monitor are set to sleep by Windows.
    6. Wake up the displays (e.g. by pressing some keys)
    Expected result: Both displays are run in the display mode as before.
    Actual result: The Dell monitor still sleeps. The notebook displays is run at a lower resolution (I guess 800x600). The Windows login prompt is not visible and it has to be guessed that it is shown. Though the typical Windows login background is visible. If the password is entered, then Windows can be used again. Though, the resolution is still low and the Dell monitor still sleeps.
    Analysis: It seems that by sending the Dell monitor to sleep, the monitor deactivates the DVI-interface or enters a low-power interface mode. This seems to disturb some component in Windows (the Presentation Director, Windows, the ATI tools, the ATI driver) in a way that Windows only activates the notebook display when it resumes from "monitor sleep".
    Suggested change: Change these tools (or the ATI driver) so that they can cope with the situation that the DVI-interface is deactivated and wait longer for the interface to be in a useable state. Reactivate an external monitor even if it "sleeps very deeply".

    Solved!
    Go to Solution.

    Lenovo support made me reinstall presentation director to rule out this component as a factor. After the reinstallation, the amdkmdap-problem is still present. Letting Windows go to standby and waking the system up afterwards, is a reliable method in my case to reproduce the problem on condition that an external monitor was active. The problem does not occur if no external monitor is present.
    A web search for "amdkmdap", "atikmpag","BSOD" with one of the ThinkPad-series names (like "T400") shows that other persons also have this problem with R400s, T400s, T500s, and W500s:
    - t400: Display driver crashes
    - W500 Display Driver
    - My W500
    - T400 Display driver stopped working...
    - T500 Video/Video Driver Issues (2056-4SU)
    - NUS T400 issues
    - T400 Display Driver Issue
    - Vista64 + 4GB RAM + External Display = BSOD
    - R400 problem report (in Chinese)
    - T500 problem report (in Chinese)
    - Bioshock keeps crashing (seems related)
    -  Vista x64, ATI graphics, dock + external LCD = bluescreens? (a report by a W500 user)
    - many problems with lenovo w500
    - another R400 problem report (in Chinese)
    -  Vista BSOD on Lenovo T500 with new Switchable Graphics
    - switchable graphics and external monitor through port replic
    - Problem with Lenovo T500 notebook & external LCD
    - Lenovo ThinkPad T400 - some impressions.
    - T400 freezes with graphics Intense programes
    - Standard Laptop mit ein paar Macken (in German)
    Some possibly related Non-Lenovo cases: 
    - Why Vista crashes so often when dual display is enabled?
    - Vista and 7.3 Display driver atikmdag stopped responding error
    - 4870 vista x64 multi-mon = atikdmag BOOM
    In the cases in which people observe the "amdkmdap"-problem and describe the circumstances, the use of an external monitor is always a factor. These other reports also indicate that it is likely not an issue with the hardware of my notebook (or then a general problem for many batches of these machine types). For it happens a) on many systems and b) on different kinds of systems.
    If others want to contribute to the problem solution, then we should provide Lenovo and ATI a good problem description. So, please add your description.
