Screen display problem with Ubuntu on SL400

I just installed Ubuntu latest release 9.04 and having problems witht he screen display. The display does not use the entire screen width. I am losing about one inch and each side. (Note that at times, the display is just right). I tried fixing it using the Display option in System but with not much succes. Any idea how I could resolve this?

Screen display problem with Lenovo 3000 N100

Hi,
My Lenovo laptop is having a problem with screen display. When i boot the laptop (keeping the screen at 90 degrees to the key board) , there is no display . However, when i tilt it down (lesser than 45 degrees) the display comes back to normal.
In addition, the mystery is that this doesnt happen if do the same after 5 minutes. No matter at what position i have the screen, it works perfect!
Is there a solution for this ? Can some one explain why the display is normal after warming up, but not in the begining (booting) stage.
Senthil.

Lose / pinched wires possibly.

I had to re-seat mine , and I still have to wiggle the upper right corner .
A common issue I here,although I just purchased a second used N100 and the screen has no issures.

Is there a way to fix ipod touch screen display problem with song list?

I was wondering if anybody has had this problem? I have an ipod touch 64gig 5th gen for probably about 2 years. I hardly use it because I have it as a back up ipod until primary one dies. This is the first time I came across this problem. Upon turning on device, the first artist/song list I choose displays correctly. Once I start choosing any other artist/song list afterwards, the display for the 1st artist/song list re-appears. If the song list is only a single song to 3-4 songs it will display correctly. Any other song list I choose that consist more than 5 songs, the first artist/song list re-appears on screen like the display is messed up.
For example: Upon turning on device, I choose Aaliyah with a list of 9 songs displaying.
Upon trying to select a different artist and song, for example I choose Nachtmar with a list of 20 songs.
The Aaliyah with the list of 9 songs re appears in place of the song list I am attempting to choose. The songs play and it works, but the display is incorrect. Why is it doing this? Does anybody have this problem? I have tried resetting and it has currently been updated. I have came across this problem just very recently a couple of days ago. I have had a couple of hard resets requiring to erase all data in the past and I don't want to go that way again because I have about 3,500 songs. I have never experience this problem before in the past. I just want it to display the current list of songs. It's inconvenient having to type in every song while playing in the car instead of being able to easily pick an individual song.

I have this problem too and it drives me crazy. When I view my ipod, I don't want to see a list of the first 8 songs in my ipod library. I just want to see the current song playing. It's like the ipod display goes into some type of "sleep" mode while your music plays,and the display defaults to show the first few songs in your ipod touch library, even though none of those songs are currently being played. I have to take the time to either flip the ipod over a couple of times in order for that list to disappear just to see the current song playing.
This is an example of what I see on my display after the current song begins playing. These are the first songs in my ipod library. To get rid of this view, I have to either shake the ipod or flip it over a couple of times and the current song is now displayed, allowing you to see the current song, also allowing you access to the arrows to either fast forward or playback/reverse. On the display, the songs are in a grid or table format (unable to show that here).

Display Problem with my Mac Pro and LG Flatron Wide Monitor in Mountain Lion

After upgrading to Mountain Lion, my Mac Pro has display problems with my LG Flatron display. The image is displayed with a black bar on the right and on the bottom. And the left side of the content is not visible. I tried every resolution available in the Display System Preferences, they are different in terms of how big the black bars are, and what part is not visible, but none of them are correct. I held down the option key to try to detect displays or switch to resolutions that are not normally available. When I restart the image is lined up with the display, but if the display ever goes to sleep or gets turned off, the image reverts to being off center, and the only way I can get it back is to restart... The interesting thing is that this monitor works fine with the same machine if I reboot using BootCamp into Windows 7. The Monitor also works fine, connecting the same connector to a Mac Mini, although that mac mini is running 10.6 and not Mountain Lion. I've reset the SMC and restarted countless times, I don't see any other levers to pull or things to try...

That card is for a PC it may not give you Startup and Option-Boot screens.
The 7950 "Mac Edition" card has a very distinctive look:

The screen shows problems with iCloud only choices are ignore or settings, however nothing I do will unlock it from this screen, cannot power off keeps that bubble on the screen. What do I do?

Try this now.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Has anyone else had a screen separation problem with the ipad?

Has anyone else had a screen separation problem with the ipad?

Does it really matter whether anyone else has? If you have, that's a problem for you whether or not anyone else has experienced the same issue. Call Apple tech support or take the iPad to an Apple Store, if there's one in your area, and they'll replace the iPad unless it's determined that the problem was caused by some sort of accident rather than a factory defect.
Regards.

Display problems with Kwin on intel hardware

Hi all,
Since the latest update of xorg and intel drivers, I have a display problem with kwin's expose-like feature. Before I file a bug,
- Is anyone experiencing the same problem? Do you have a workaround?
- Does anyone know what could be at fault?

I will, and I hope you'll contribute your logs to the bug report! The question is where to submit it: I'm pretty sure the bug is upstream, but is it a kwin bug or an xorg/intel bug?
Ctrl+F11 works "fine" on my system, even though it crashed kwin the first time I tried it :-)
Well, that's a very tough question! I was thinking to fill a bug report in Arch's bugtracker, although I also think it is an upstream bug. Problem is, after reading this http://blog.martin-graesslin.com/blog/2 … paces-4-5/ and this http://www.itnewstoday.com/?p=1803, one can realize the absolute *Mes(s)a * that dominates the whole graphics stack....

External display problems with snow leopard

I just upgraded from Leopard to Snow Leopard on my Macbook and it's created lots of problems with my LCD external display:
- The display won't work at its native resolution (1680x1050) - it will flash up an image for 1/10 of second and then go black. I can only get it to work at a lower resolution, which looks AWFUL.
- If I try to start up my Macbook with the lid closed and the display connected, the display won't work at all (it jams on the start up screen). It only works if I keep both of them running
I never had these problems when using Leopard. I've searched lots of forums and found that many people are having similar problems with external displays. Apple still haven't fixed the bug after repeated efforts from people to get if fixed.
Here are some threads (now closed) on this if you're looking for solutions:
http://discussions.apple.com/thread.jspa?threadID=2132912&tstart=0
http://discussions.apple.com/thread.jspa?threadID=2136455&tstart=1
http://discussions.apple.com/thread.jspa?threadID=2132837&tstart=0
http://discussions.apple.com/thread.jspa?messageID=10084332
Common suggested fixes are:
- Force OS X to use LCD font smoothing (does not work for me)
- Clear the PRAM on start-up (does not work for me)
- Delete /Library/Preferences/com.apple.windowserver.plist (does not work)
- Change energy management setting to high performance (only works on graphics cards in Macbook 15" and 17").
From reading these forums it appears that this is a well-know bug. Has anyone else got any suggestions to fix this? And why hasn't Apple fixed this yet after so many people bringing it to their attention? It's clearly a bug that wasn't in Leopard.

I'M FED UP WITH APPLE! They've always been a little shady, but the last half of 2010 took the cake!
First it was the iPhone 3g "upgrade" to IOS4 which was garbage and killed my ability to use the 3g until I figured out how to crack the software, wipe the thing clear then reinstall the original software. Next up was purchasing the iphone 4 as a Christmas gift for someone running tiger on their mac, only to find out that the iphone 4 doesn't work on tiger when they tried to sync their contacts - and then having to rush out and purchase snow leopard so that they could enjoy my gift. Then I install Snow Leopard (note - I purchased the family pack) onto my own leopard-running(10.5.+) powerbook only to have the external LCD display I've been using for years suddenly stop working.
Oh, okay, to be fair, it works IF I RESIGN MYSELF TO SET it to "mirror image" (which defeats the purpose of having multiple displays) and drop the resolution down to a pathetic, unsharp, nearly distored setting that is almost painful to look at knowing that this monitor was just A COUPLE OF DAYS AGO showing me crystal clear images.
Then I exhaust myself trying to find a fix only to discover that APPLE in their infinite brilliance (AKA - their torture of loyal customers) knows of the issue - worked it out - then created an update that created the issue all over again. I'm so done! No more macs. I'm going back to the evil land of PCs. At least there, you know you're getting crap, it doesn't sneak up on you after getting you to trust it time and time again.

Two display problems with my new MacPro! :/

I recently bought a new MacPro to replace my PowerPC, and am having some odd video problems I did not have with the old computer (yes, using same display). Here's some quick stats I think are important.
1. 30 inch Apple HD display (used on both computers.)
2. Old video card = Radeon X1900 - NEW video card = Geforce 8800 GT (came factory installed)
3. Old OS = 10.4.11 Tiger New OS = Leopard (with all current updates. Also factory installed)
4. Quicktime Pro on both systems fully updated
5. Both Machines had all updates installed at the time of this problem (which is since i got the new machine)
Here's the two problems...(btw NEITHER of these happen when the display is hooked up to the old computer. only the new MacPro with a different video card and OS)
1.) When I play back video (sometimes in FCP (all types of files), sometimes in QT (.mov), and sometimes even on youtube and vimeo (so those are .flv files!) only SOMETIMES do I get these odd vertical refresh-looking lines. It makes the video somewhat flicker and you can see them crawl upwards kind of. The odd thing tho, is if I play that art of the video over and over, at times it will happen, and at other times it will not. same file, same part. I also noticed it does NOT stay on the file when exported from FCP and burned to DVD, so I'm thinking it is purely playback.
2.) Some files when played back in quicktime will get extremely choppy. (Locally played files). I will then click the desktop to make finder the front most selected program...and the files will then play smooth. if I select the QT window again, it will get choppy and flicker again.
I feel like I have a refresh rate problem, or maybe even a driver problem. The thing is, of course the drivers are not updated outside of auto updates, and I have installed everything available there.
When I open up my display settings, the refresh rate box is grayed out...so changing the rate isn't possible. Also, with my old computer/video card, I had an ATI control panel...the geforce does not have one...only the build in OSX display control panel.
Has anyone heard of this? I have posted in a few different places, and have received absolutely no replies. It's really frustrating, and sitting on the phone for hours with apple support to have them say "never heard of that problem" or have me lug the **** thing into a apple store and be without my computer and unable to work doesn't sound fun either.
it's not stopping me from doing anything..it's just annoying and frustrating cause I can't make it stop. I'm thinking it might be a problem with the leopard drivers that hasn't been addressed yet? I dunno.
Any suggestions?
thanks in advance,
Damion

UPDATE ::
In reading an old solution on how to get rid of the dancing pixels I get every once in a long while on this display, I downloaded SwitchResX and am using the demo to test and see if switching the refresh rate to 58khz will help in the line problem...and lo and behold...it kinda does. it is now only noticeable on fast moving action when put into full screen mode.
The QT flicker problem has NOT gone away...but I'm expecting that the horizontal lines running vertical are a refresh rate problem as I had thought.
My question, anyone know if apple is aware/working on this?
Also, why is the refresh rate not changeable with the 20 inch HD display settings in the display control panel??
I'd much rather use OSX to control my display than a 3rd party application! :/

Experiencing display problems with InDesign CC under Windows 8.1

I have recently installed Adobe InDesign CC, and have experienced problems with the screen display when running it including pixelated icons and tool bars, in addition to text and image boxes that float whilst hovering over them with the cursor.
I have not experienced similar problems with any of the other Adobe programs installed.
Thank you.

No, but I just managed to sort the problem out. I ran the compatibility troubleshooter, and the program is now running in the compatibility mode for Windows 8, and everything appears to be OK now.
Thank you for your time and feedback.

Screen/display problem

I have a problem with my screen/display on a four year old Macbook Pro running OS 10.6.8. Sometimes it goes black but isn't really asleep, just very dark, but I can't wake it up or brighten it. I have to force it to restart. It also gets vertical light patches in the screen, which I can reset using keystrokes, but it still recurs sometimes. This is starting to happen more often. Any ideas what the problem might be?

Could be LED board has a bad back light, logic board is on the way out. Take it to an Apple store, they have a flat repair rate, it's worth a trip ,as they do a diagnostic for free. I had the same issue and they repaired a bunch of stuff for the flat rate, which is about 1/3rd of the cost of the cheapest MBP.

X60 - Screen flickers and screen shutoff - problem with power management or hardware failure?

Hello everyone,
this is one of the longest unsolved threads in Lenovo Forum. To keep a summary of the posts for new victims (as suggested by PDG in page 23, edited by me):
Bottom line:
This is a video driver problem
If you have XP and can, roll back to 4450 (I currently run with 4860 in XP without problems)
If you have Vista you are basically screwed. No one has posted any link to a functioning V32 driver.
You can find a link to a backlevel XP driver on p.21 or thereabouts.
{Windows 7, Linux} may or may not help. (no problems for me with Ubuntu 8,9 currently)
LENOVO WILL NOT HELP. Don't waste your time. Lenovo will say its a hardware problem because that's all they know and charge you big bux to do basically nothing when you ship them your PC.
This is the original entry:
Hi,
I always stay at the current level of available drivers with System Update.
In the last days the screen starts to flicker / jiggle once in several minutes until suddenly the whole screen turns black and can't be reactivated. I then put the X60 into standby and it wake up right after. The screen is then turned on again...
Its a 1706-AA7...
I rolled back the graphics driver to an earlier version, didn't help. Does it look like some faulty power management? Or a potential HW issue?
dsp
UPDATE: this time the screen was totally light blue... same workaround: standby -> wakeup
UPDATE2: I removed the driver completely and installed it manually from the driver matrix page. It took a couple of reboots. In between resolution was down to 640x480 with 4 bit. Not its working again without flickering...
Was this a wrong driver pushed via System Update?

Solved!
Go to Solution.

Hi,
no - 2 video adapters are correct! You should not remove them. Read the Intel FAQ here.
Strange - could it be that it also updated your video driver the same time? When I rolled back the video driver to a very old version, I never experienced the flicker again. No colorful blanks anymore.
The Intel downloadpage offers a backlevel driver for the chipset;
* Microsoft Windows* XP
* Driver Revision: Production Version 14.32.3
* Package: 43262
* Graphics: 6.14.10.4906
* HDMI Audio: 5.10.0.1030 But I don't know whether I should try. This release doesn't appear in the Thinkpad video driver history. Hopefully the bug will be acknowledged and they work for a fix. Where should bugs be reported, when they are not taken serious by the first level support?

HT201257 Screen/ Display Problems- maybe hardware related?

Has anyone experienced a problem with their display- where an open window repeats over and over the entire screen (sometimes appearing like random squares) and the only way to correct the display seems to be by opening finder and dragging it across the screen? This often occurs when using CS5 inDesign.
Does anyone have a solution/ diagnosis?
Thanks in advance!

That sort of problem correlates with a graphics Hardware problem.
It is possible that if your graphics card is clogged with dust, blowing out the dust and allowing it to stay cool will resolve the problem, but I would not get my hopes up.
The Apple 5770 works in all Mac Pro models, about US$250. Do not buy a non-Apple version, as it will not show a picture under Mac OS X.
