Ubuntu Installation :: Some Screen Resolutions Don't Work In 11.04
May 5, 2011
After upgrading from 10.10 to 11.04, I find that I can not successfully set the screen resolution of an external monitor to 1280x1024, for instance. The screen draws blocks of graphics in strange places & doesn't seem to erase properly. This screen resolution worked in 10.10, as did all the display options. However, now that I've upgraded only resolutions of 1024x768 & lower work OK. Is this is a bug in 11.04? My hardware: Dell Inspiron Mini 10v, Intel Atom CPU N270 1.60GHz, 1GB RAM

My screen resolution for the computer is 1600 x 1200 which is what I want but for my internet the resolution changes to something like 800x600. It happens in firefox in ubuntu and it happens in explorer 8 in vista. I just used clonezilla about a week ago. Now this is what is happening on the new cloned drive?

I have a problem with Plymouth. It works pretty well on low res, but on higher resolution some strange video artefacts appear - see attachments.
I use ATI proprietary drivers, if it has something to do with it.
The resolution is set in /etc/default/grub like this:
Code:
GRUB_GFXMODE=1024x768
GRUB_GFXPAYLOAD_LINUX=1024x768x32
edit: reducing colour depth doesn't help /end edit
I don't know whether it has anything to do with the current problem, but Plymouth used not to appear at all until I followed these instructions (or actually I took them from another thread but I can't find it at the moment and these are the same).
I don't know whether it's possible to take them during booting so I've taken these photos with a mobile and retouched in gimp to remove reflections (more or less), and since I'm no pro photographer nor photoshop/gimp master they look as they look. They should do to demonstrate the problem, though.

I use a 17" laptop with a 22" secondary monitor running Ubuntu 10.04 LTS. The res on the laptop screen is 1440x900 (16:10) and the secondary monitor mirrors this. Problem is that because the secondary monitor aspect ratio the display is somewhat distorted. It's not so bad that it is unreadable but I work in IT so I am at my computer for around 8hours a day so it wear thin after a while.
Is there a way for me to set different resolutions on each screen? The laptop have an ATI Radeon Graphics card and cannot change the Resolution above 1440x900 even within ATI Catlyst control center.

Under system > preferences > monitor I can select either 640 x 480 or 800 x 600 or 1024 x 768 which are all 4:3 aspect ratios, as my screen is 16:9 everything looks stretched. How can I set a 16:9 aspect ratio screen resolution?

Linux Ubuntu 9.10 (karmic), Nvidia g-force 5200, Intel(R) Pentium(R) 4 CPU 2.80GHz(old PC but i need learn Linux inside out b4 I go 100% Linux)But I have taken the time to the learn the basic cmds like man mv cp apt-get install etc. I cisco engineer but I want to get good with Linux distro's.I have a NVIDIA G-FORCE 5200 which according to NVIDIA'S website the 173.14.x.x driver is the correct one.I have tried diver 173.14xx. I installed it manually and restarted x server.
I have read the installation guides on this forum but to no avail.When I reboot Compiz cube features are working BUT my screen goes 640x350.I tried to edit the /etc/X11/ xorg. conf file but I cant see any screen resolutions lines. I tried changing NV to nvidia and visa versa. Still the screen is buggered.I installed compiz checker and ran it it said all ok. My text goes large the colours are jittery ? When I go to NVIDIA XSERVER SETTINGS i can not change the screen res ? It just stops from selecting the options? I also tried driver 185.18xx and the same results.I also tried installing the drivers with Envy NG and still no better.I now have installed 96.43.13 NVIDIA driver and my screen has went back to normal but I can not enable the cube effects. I take this means it has reverted back to the graphics card on the motherboard? I have also looked at xrandr -s <1014x768> cmd to manually change it and again no avail.

I generally suspend between work sessions. Occasionally, after a long time of running, my display goes black and is unresponsive. This seems to happen when I have fallen asleep while working. Now, I don't think someone has sneaked in and done something to my computer! Anyway, all the applications are still running (observed by bringing up the console, top/ps) but the X session does not respond. I have tried the Control-Alt-Backspace keystroke that is suggested for restarting X Window.
Over several times, I have experimented with killing specific processes from the console to see if I could restore life to the session, without having to shutdown. Today I noted that if I blast the compiz process it did come back. Of course, there may well be a specific combination of steps I did before that step that resulted in it working.

I just upgraded to an ASUS MS227 on a Ubuntu 9.10 box with a "NV34 [GeForce FX 5200] (rev a1)" video card. Here's the problem, the only two resolutions it will work in is either 1900x1200 OR 1440x900. Anything in between shoves the display about 5 inches to the left, so far over that it's not correctable by the monitors own horizontal control.
This is my xorg.conf:
Code:
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
SubSection "Display"
Depth 16
[Code]...

I'm fairly new to Fedora. I am using F14, on a brand new laptop. The LCD screen needs to be matched with a 16:9 ratio, or it stretches everything out. Unfortunately F14 only comes offering three options... none of which are 16:9. Is there an easy way for me to add a 16:9 ratio to my display settings? Does it matter that I am running in low graphics mode?..... it's the only way the liveCd would install.

I have 2 screens connected by vga/dvi and need to use different resolutions...at the minute ubuntu is forcing the same for both. Where should I start looking. I have two video files recorded simultaneously. I want to edit them into one video file with non-standard resolution and a split screen view which, two videos can be seen together. I tried kdenlive but I was unable to change the output resolution.

I installed Natty on a 5-year-old Compaq with an integrated Intel 8xx chipset, using a Polaroid TLA-01511C monitor, and the list of available resolutions varies quite a bit each time I boot. Sometimes it will only give me 1024x768, 800x600, and 640x480; sometimes it gives me a dozen resolutions ranging up to 1600x1200. Only once has it ever offered me the monitor's native resolution, 1280x800.
I'm guessing the EDID is being missent or misread each time. How can I set it to (ignore the EDID and) allow me to select 1280x800 each time? I did notice that when it was a Windows machine, it would give me the short list of resolutions when booted with the monitor off, but gave more options when booted with the monitor on. Here though, it seems to give the long list when booted with monitor off.
Here's my most current /var/log/Xorg.0.log; this time it booted with about a dozen modes available, but not 1280x800.
Code:
[35.690]
X.Org X Server 1.10.1
Release Date: 2011-04-15
[35.691] X Protocol Version 11, Revision 0
[35.691] Build Operating System: Linux 2.6.24-27-server i686 Ubuntu .....

I am running CentOS within VMWare on my Lenovo T61p laptop. This laptop has Windows XP Pro installed on it. My problem is that the resolution in CentOS within the VMWare is way to small. There are only two selectable resolutions, both are way to small. How can I get additional larger screen resolutions?

One day, when I switched on my notebook Lenovo X400 with Suse 11.3 I observed that the graphical login screen is divided vertically into two equal parts - each in different resolution. There are also two mouse pointers. They work simultaously (eventhought I can see only a half of each). The problem is that when I login there is no effect, it goes back to login screen. I can login into text terminal. But if I go to "init 3" I still can not startx and the next time I reboot the same problem comes again. Shall I somehow reconfigure X windows or method of logging in?

after installing Natty on my brand new shuttle with Intel's Sandy Bridge Core i5 (2500K), everything works fine except setting up a higher resolution fitting to my screen.All I need is a 2048x1152 resolution, but all the display configuration in the hardware section of the system settings offers is 1024x768, 800x600, 848x480 or 640x480.The monitor is connected via VGA since it doesn't have a DVI or HDMI plug.Is there a way to tell the system there is more capability? Do I need a different driver? What and where can I check this?

I have been using Ubuntu for a while with no real issues. I have tried to do a fresh install of Kubutu but I cannot install it due to the fonts on the installation process being tiny. I am using a HDTV as my monitor so could this be the problem?? I have no other monitor to utilize so where do I go from here?

I can't get the Ubuntu 10.4 Live CD for PPC to work on my old 800 MHz flat screen iMac G4. I believe it's supposed to work, but the installation dies with a magenta screen about a minute after selection of any boot option in the yaboot dialog.I tried all the sensible boot choices and options, all with the same result: some trundling of the CD reader, display of the messages related to the ramdisk, more trundling, then a blank magenta screen and no more trundling. The iMac becomes totally unresponsive: no more messages, can't enter any command shell. I get the impression (complicated story) that it begins to install the X server and then aborts.
This iMac has a PPC G4, 512 MB of working memory, and a GeForce2 MX video card with an nVIDIA chipset and 32 MB of video memory. There seems to be no hardware problem: OS-X 10.3 and OS-9 run just fine including wireless networking.

I'm trying to install Ubuntu on a Dell computer of mine but I can't get it to boot past the loading screen. I'm using 10.04 live CD. At the loading screen (boot, memory test, etc..) I select to boot the live CD and after that, I get a black screen followed by no signal from my monitor. My monitor is a 42" LCD TV (I had plans to turn this PC into a HTPC using Ubuntu and Boxee). I know Linux will work on this box, because it has in the past. Now, before I used to have an ATI Radeon X 1300 PCI-E card and now I am using an ATI Radeon 2900GT, and since cannot boot.
Does anyone have any idea on how I can get this to work?

I'm running Kubuntu, OS Version: Linux 2.6.35-28 generic KDE SC Version: 4.5.8
I have a large monitor, and the max resolution of KDE (1280 x 1024) doesn't fill the screen. That seems rather small for a max resolution. Is it possible to get a larger one?

After struggling with this for 2 days and getting nowhere, I found this simple solution.
1. Download packages http://ajoliveira.com/ajoliveira/gen...it_9.10.tar.gz and http://ajoliveira.com/ajoliveira/gen...rg.conf.tar.gz.
One of these contains the driver files and the other a xorg.conf file.
2. Extract the 2 archives by double-clicking on them.
3. Copy the xorg.conf file to the /etc/X11 directory code...

I am running Ubuntu 9.10 on an HP laptop with an Intel 82852/82855 GM/GMC Graphics controller. I have a 2nd monitor attached to the VGA port (HP f1703). The problem is that the two screens have different resolutions. the laptop is 1280 x 768 and the other monitor is 1280 x 1024. The xorg.conf file that was created with Xorg -config set both monitors up with 1280 x 1024 resolution so my screen on the laptop looks all "squashed". I have tried to reconfigure it using the Display Preferences dialog but after i re-boot, both screens are unviewable and I have to restore my previous xorg.conf file. I went through the HOWTO: Jaunty Intel Graphics Performance Guide procedure to setup a "safe" configuration but didn't work and I had to restore my "good' xorg.conf file. What do I need to do to setup my two screens with the correct resolutions: 1280 x 768 and 1280 x 1024?
Here is the video portion from my "good" xorg.conf file
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
EndSection

I have recently installed Ubuntu 10.10 on my computer. The default display driver supplied with it only allowed the screen's default resolution (1280x1024), so I downloaded and installed nVidia's latest driver (260). When I change the resolution to anything lower than the default, the graphics (and most notably letters) everywhere appear slightly blurry, becoming more and more blurry as I lower the resolution. The blur is not terrible, I can still use it but it becomes annoying to watch after a while. I am using a GT240 graphics card, and this problem does not exist on Windows using the same resolution and same driver version.

I'm trying to add a higher resolution to my system. I've tried to edit xorg.conf but I think I'm wrong. Everytime I edit and reboot, it tells me I need to run in low graphics mode for now. Now I'm trying 'xrandr.' I was able to create a new mode just fine, but when I try to add it to the appropriate output, I get this:
Code:
prog@ubuntu:~$ xrandr --addmode LVDS1 1280x1024_50.00
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 149 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 25
Current serial number in output stream: 26
Here's what xrandr returns:
Code:
prog@ubuntu:~$ xrandr

I don't know why it puts it in TV1. There's two of them because I tried two different refresh rates.
