[SOLVED] Cannot Change Screen Resolution

Today, I reinstalled Arch — I replaced the Windows partition with a new / partition, and the old partition became /home. Now, with the new installation, in X, I cannot get a resolution higher than 1024*768. xrandr lists 1280*960 among others, but if I try to switch to it, the video card stops sending the video signal to the monitor and the only way out is to raise elephants.
Hardware:
Video Card: NVIDIA RIVA TNT2
Monitor: ViewSonic A70f+
I am using the nouveau driver for now. In the old installation, I believe I was using nv.
How do I fix this?

Adding nomodeset fixed it. The resolution is now a surprising 1400*1050:

I didn't know my monitor was capable of 1400*1050. I thought its maximum was 1280*1024.
It also got rid of the framebuffer... heh heh
I also switched back to the nv driver.
[2010-12-19T12:19-0600] Update: That's odd... It went back down to 1280*960. Oh well, I originally wanted that resolution anyway: http://img.ly/system/uploads/000/632/75 … _scrot.png

Cannot change screen resolution in VDI

I have set up a test VDI environment. Each user is manually assigned to a virtual desktop. Here is the issue. I am unable to change the resolution for the user. It goes to full screen and fills both monitors. But the user would like resolution to be a
little lower. Do I need a RemoteFX 3D adapter to accomplish this?

so it helps to write all detail in the question :-)

Cannot Change Screen Resolutions

I recently upgraded to Tiger and noticed that I can no longer change the screen resolution. There is now only one choice 1152 by 768. I have reset PRAM and installed the latest ATI software with no solution. Also software which used to run in "full screen" now only runs in a much smaller window.
Any ideas?
Thanks - Bill

Hi Everyone,
This seems to be a common problem that is plaguing 800 & 867mhz TiBooks. I am an ex-Mac Genius and have tried to fix this on my machine to no avail. It worked once, but after I used the S-Video port the problem returned. Here's some of the stuff I've tried. I'm not going to explain some of these procedures as they are all well documented troubleshooting procedures. Just search for them here on the Apple Support Website & on MacFixIt.com:
NVRAM & PRAM resets
power manager resets
Permissions Repairs
Disk Utility Repairs
Diskwarrior 3.0X
Cache Deletion using Cocktail (available at Versiontracker.com)
Deleting Kernel Extension's Cache
Deleting Displays preferences
Reinstallation of Displays Bundles from Install DVD (/System/Library/Extensions/AppleNDRV/)
This one is nasty. It seems to be directly related to the Radeon 9000 & the way that the System Software verifies what kind of Display and Video Card it's using. I had also Installed ATI's Graphics Update which they said was Tiger compatible. However, the software doesn't allow any advanced options after this bug has struck. I uninstalled the ATI Software manually before I replaced the System Bundles.
I have sent a bug report into Apple and wanted to post some off this info here in hopes that maybe some of this will help some of you. Like I said I had fixed this briefly, but after using the S-Video port it came back, which is why I think it is a problem with the System's ability to recognize the Video Card & Display.

Cannot change screen resolution on an Ultra 5 using m64config

I have an Ultra 5 with Solaris 2.6 connected to a Xerox XR6-19Dw 19" widescreen monitor with 1440x900 pixels. This workstation was set up a long time ago, so I do not know exactly how it has been set up. The screen resolution is set to 1280x1024x60 and it looks very blurry due to the mismatch between LCD pixels and the resolution setting. First I tried m64config -res 1440x900x76 try. This just turns the screen all white, luckily it reverts to the old setting after 10 seconds. Then just for fun I tried m64config -res 1280x1024x60. This also turned the screen all white. I have heard there is also a way to set the screen resolution using the boot prom, but that this is not necessary because m64config should work. It is very important that I do not mess up this workstation, but the eyestrain is a big problem. Is there a safe way to fix this?

Get a different monitor. Use one that is far less capable and has an old-style 4:3 screen ratio (not a wide screen).
The integrated graphics of the Ultra5/Ultra10 platform has only 4MB of frame buffer RAM and defaults to Sun's screen output of 1152x900 at 66Hz refresh. In fact, very early Ultra 5 systems had only 2MB of frame buffer RAM for the integrated graphics. The hardware is incapable of providing anything like what you are asking for.
If you don't care about color depth, the 1280x1024 resolution you currently see is the highest you're going to get. There is absolutely no chance for any wide-screen settings. If you ever hope for 24bit color, you will have to go down to the 1152x900 setting or more probably down to 1024x768.
You're system is a design from 1997 that first shipped to paying customers in 1998.
I think you are hoping for too much out of that dinosaur.

Unable to Change Screen Resolution in Remote Session - Windows Server 2012 R2

Does anybody know of a way to allow Remote Desktop users to adjust their own screen resolution in a remote session under Windows Server 2012 R2? We are struggling with this and can't seem to find a solution.
When users login to their RDP session and try to adjust their screen resolution this message is displayed in Control Panel:
"The display settings can't be changed from a remote session."
We don't want to use the "make text and other items larger or smaller" scaling feature, as this produces undesirable results with some of our applications. We also don't want to have to support multiple types of RDP clients or RDP shortcut
files.
We have looked at other posts but can't find an answer that applies to Windows Server 2012 R2. The closest thing we could find is KB2726399, but it only applies to Server 2008.
Does anybody have a solution for Server 2012?
Thanks

Hi,
Currently you cannot change the resolution from within the session. This is normal and expected behavior.
Unfortunately this means you need to set the desired resolution before connecting by using custom .rdp files, manually within the Remote Desktop Client, custom web launch page, custom windows launch program, etc.

Change Screen Resolution or not Change Screen Resolution?

I mean is it possible to change screen resolution with Java?
I read some topics (not in this forum) that is impossible. I know there is a method to set at full screen a frame with the favourite resolution but does it effectively exist a method to set the screen with a favourite resolution?
For example:
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setUndecorated(true);
        frame.setIgnoreRepaint(true);
        device.setFullScreenWindow(frame);
        if (displayMode != null && device.isDisplayChangeSupported()) {
            try {
                device.setDisplayMode(displayMode);
            } catch (IllegalArgumentException iae) {
                System.err.println("EX: " + iae);
        ...the device.setDisplayMode(displayMode) always throw me an exception: Invalid Display Mode (or something like that) with all permitted display modes (640by480, 800by600, 1024by768, etc...), with all permitted refresh rates, with all permitted color depths.
Illuminate me please!
Thanx in advance!

Post relates to: HP TouchPad (WiFi)

Sorry to say reloading WebOS did not help this issue on my TP. contacted Support and was told to send it.Even sorrier to say that my TP is now lost. My tracking number reports it as delievered on Dec 5, but HP has no record of it.When I got back on Chat they are now also telling me that my TP serial number is a EU model, even though my box clearly states HP Touchpad ,US, 1.20,32gb,Wifi.
Not sure what that even has to do with it being lost now..if it is as they say and no warranty on it in US I just want it sent back.

Another feature to allow users to change screen resolution to HD for gaming

I liked k3 Note, smartphone which is filled with lots of professional features. Can you add a control to change screen resolution to HD for games. Lots of people are there which are thinking that other phones' gpu are better and the Mali t760 m2 not so good.

Hi
In case someone else encounters the same problem, here is some more information.
The high refresh rate is quite visible in Device Manager. It would refresh every one or two seconds. The cause seems to be a conflict between a Fingerprint software installed during the Task sequence and the Validity Sensors Drivers.
I made a Scan for hardware change in Device manager and saw that a few devices were appearing as unknown. Right click, update drivers from local cache solved the problem.
I cancelled install of the fingerprint software and did not encounter the problem anymore.

Problem to change screen resolution in MB Intel DG41 with video on board

Hi, I need some help as soon as possible because this problem it´s make me difficult my job. I have installed the MAC OS Snow Leopard 10.6.2 in a Motherboard Intel DG41 with micro Core2Duo and video on board of this motherboard and don´t let me change screen resolution. I have a display of 22´ inches and the panel to change the screen resolution only mark 1024x768. I think the more likely it is that the system does not recognize me the drivers to this chipset of video. I searched everywhere on the internet but I have not found the solution.
Thanks Fernando

Changing screen resolution with xrandr [SOLVED]

My current setup consists of two different monitors (different resolutions) being connected to a single Nvidia card (neouveau driver).
The problem is that the monitor resolution does not change when I use xrandr to change the resolution. What does happen is the resolution of the output changes so that all items on the screen are smaller, but as a consequence of the monitor resolution staying constant (at 1440x900) this also leads to everything getting blury.
Output for xrandr after booting:
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192
DVI-I-1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 360mm x 290mm
1440x900 60.2*+
1920x1080 60.0
1280x1024 75.0 60.0
1360x768 60.4
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
DVI-I-2 disconnected (normal left inverted right x axis y axis)
Output after changing the resolution to 1920x1080:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
DVI-I-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 360mm x 290mm
1440x900 60.2 +
1920x1080 60.0*
1280x1024 75.0 60.0
1360x768 60.4
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
DVI-I-2 disconnected (normal left inverted right x axis y axis)
I have set up both of these monitors to work fine today, except for the resolution problem. The DVI-I-2 seen has a maximum resolution of 1440x900, which is what both monitiors are running at although DVI-I-1 has a max of 1920x1080.
Does anyone have any ideas on how to succeed in setting DVI-I-1 to the desired resolution?

Yes, GPU support for dual head is there. I think I will try out the Nvidia drivers.
Edit: I have installed the Nvidia driver and everything is working perfectly. Thanks for your suggestion.

[SOLVED] Changing screen resolution with xrandr.

Been googling around after a way to change my screen resolution.
I'm on a Acer Aspire Timeline 3810t with the resolution 1366x768.
I wanted to change my resolution to something like 1900x1200 and found a guide explaining how to do this with xrandr.
This is what I did:

Good, you've learnt to use the wiki, please do that first from now on (google as well). Also, please use code-tags, makes it easier to read code/conf-files.
It looks like you're trying to set your laptop screen to a resolution higher than it can go. Hint: not possible. If you had an external screen with a higher res then you could use that, but the resolution is limited both by the screen and the graphics card, and I haven't heard of any laptop screen with such a high resolution.

Changing screen resolution

Hi Everyone,
I'm quite sure that it is not possible to change the screen resolution from within a running java program. The problem is that my boss won't believe it until he reads it in the spec. Does anyone out there know where to find a anything about it the specs?
Thanks in advance
jan

Hi! The screen resolution is a function of the underlying OS and cannot be changed from a Java program, unless one resorts to JNI. However, the screen resolution can be retrieved from a Java program. Look at the docs for the getScreenSize() and getScreenResolution() methods in the java.awt.Toolkit packges. Note that these methods are abstract. The actual implementation depends upon the vendor.
Perhaps you can ask your boss to search the Java docs for methods that allow Java code to change the resolution w/o resorting to JNI. We'll all be glad to know! :-)
Hope this helps!
Cheers!

Change screen resolution on netbook

I've just installed arch linux with xfce. When I try to change the resolution, the only options are 800*600 and 640*480. It also does not recognize my external monitor. How can I fix this?
Thanks

JorisL, usually we cannot support ArchBang specific problems. You should really ask on the ArchBang forums as well as this can be distribution dependent.
Usually we will close this kind of thread according to our Forum Etiquette. I will keep this open as perhaps some solution is underway. If there is such, please tell the people at the ArchBang side about this as well. (Do so here, too, i case you'll get some solution over there.)
And do not forget to mark this thread [SOLVED] once your problem was fixed.
