Ubuntu :: Lost The Higher Resolutions For Computer?
Apr 30, 2010
I lost the higher resolutions for my computer. The highest available is 1360x768 (which doesn't work well) and currently I'm using 1024x768. Before, I had 1280x1024 working well and I even had higher resolutions available in nvidia-settings. I've ubuntu 9.10 with nvidia drivers (185.18.36).
I've read [URL].. but not necessarily all of it or understood all of it. I've tried dpkg-reconfigure xserver-xorg and the xrandr stuff but nothing has changed, except what xrandr reports, regarding the addition of two modelines 1280x1024. In the end, I suppose something has corrupted some file but how can I figure it out?
Code:
Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1280 x 1024
default connected 1024x768+0+0 0mm x 0mm
1024x768 50.0*
800x600 51.0 52.0 53.0
680x384 54.0 55.0

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'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
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096

v: height 1024 start 1025 end 1028 total 1054 clock 50.0Hz
I don't know why it puts it in TV1. There's two of them because I tried two different refresh rates.

Just bought a new 1080p monitor (1920x1080) and it works fine in OpenSUSE 11.3. Problem is before I get the KDE start screen everything is not full screen. Now, I checked the rest of the forums and I cannot find a full list of widescreen or 16:9 grub resolutions.
Does anyone have a list of what's supported?

I recently got a new external monitor for my laptop, and connected them by VGA. This is what 'xrandr' tells me:
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096
LVDS1 connected (normal left inverted right x axis y axis)
1280x800 60.0 +
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 510mm x 290mm
1920x1080 60.0 +
1600x1200 60.0
1680x1050 60.0
1280x1024 75.0 60.0
1440x900 75.0 59.9*
1280x960 60.0
1280x800 59.8
1152x864 75.0
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
However when I try to change to some of the higher resolutions, such as 1920x1080, all I get is a corrupted and flickering image. As indicated above, I am currently on 1440x900@59.9h,z but for some reason 1440x900@75hz doesn't work. The same seems to be true for 1280x1024. The three resolutions above that all cannot be selected properly. I tried setting the resolution to maximum in Windows XP and it worked, and my video games console can set it to 1080p, so I don't think there is anything wrong with the monitor. Is there anything I can do or is this some kind of bug or limitation of the graphics driver or something? The graphics chipset of the laptop is an Intel 945GM, which I believe should be capable of displaying 1920x1080. I am running debian unstable with what seems to be the most up to date version of xserver-xorg-video-intel.

Just did a new install of 11.4 over top of my 11.3 and when I reboot into the OS it seems to boot just fine but the video is unreadable. When I boot into the failsafe the screen has a lot of gitter and the monitor tells me it's not in preferred mode of 1680x1050 at 60hz. All resolutions higher than 1280x1024 are unreadable. Tried booting nomodeset as I've read previous ... no luck. I'm still learning linux.

So I have been running uvesafb for a while now with no complaints, but klibc hasn't been updated for about a year. I contacted to the author and he said that he will have an update in the coming weeks. However today I was googeling around and to make a long story short, I have successfully been able to get a 1920x1200 console resolution with just the plain old vesafb. This is good news but I am also confused because I've been told many times that is not possible for vesafb to do higher/wide resolutions.

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 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'm using the 270.41.19 nvidia properietary driver for my Geforce GTX460 graphics card. I have a Sony TV connected to my HDMI and I know it supports the 1920x1080 resolution. Yes it works after gnome or other DE loads up.
But during the GRUB screen and the bootup console - It defaulted to a 640x480 resolution (as it always does with the nvidia prop driver). I usually used to check the output of hwinfo --framebuffer and choose the resolution by appending the right vga=0xabc parameter.
But now I have a problem since hwinfo says the best widescreen 16:10 framebuffer resolution that my card supports is 1280x800. Here is the output from hwinfo --vbe which should give the info about both my gfx card and my TV.
The initial nouveau driver was able to output native 1920x1080 during the bootup on the console without issues, so I guess even the properietary driver should be able to output (If my understanding is right the nvidia module loads later during the bootup and only is required for the X but not for the console itself).

for christmas my parents got both my younger sister and i acer mini computers, model d250-1958. my sister was trying to change her password that lets herself as a particular user log in. somehpw she messed up the password and its not what she thought it was and now she doesn't have any way of accessing anything. i thought that there might be an ovveride system or a reseting trick. i've looked in the manual but cant find anything of the sort for either of the two options.

I was running OpenSuse and realized that I hated it. I backed up my bookmarks to a USB flash drive, formatted and installed Ubuntu 10.04.
On entering Ubuntu, I stuck the USB flash drive in and realized that the bookmarks never got copied. I've lost them. I have to have those bookmarks. What would be the best way to get them back?

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.

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?

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?

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.

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.

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 collection of *.mkv files which are 720 HD resolution (1920x720). I'd like to watch them on my netbook, but it can't handle HD content. The videos play fine on any decently-powerful desktop, under either Windows XP/7 or Ubuntu, but they are simply too much for the Atom CPU of the netbook.Is there a way to downconvert the .mkv files to something the netbook can handle? It doesn't have any problem with standard DVD content, which is of course lower resolution. Cutting HD content down to the netbook's native resolution(1024x600) would probably be sufficient.
A free software package available in the repositories would be great, but I have no problem manually installing something if necessary. I have not done any work with converting videos to different formats, so I don't know what's out there for Ubuntu.

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

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 have two monitors of different resolutions. Under settings->display the settings for my monitor look like this: [URL]. Ultimately what I want is to set up this kind of configuration: [URL]. But whenever I do, it doesn't work out. When I up after setting the above settings, my configuration ends up like this: [URL]. Any attempt to change the resolution or to change the display type to anything other then clone is simply ignored. If I disable the second monitor I can set my first to the proper resolution. If I try to set the settings to what I want they will stick but the second monitor doesn't actually turn on, and if i try to drag windows that direction it acts like a single display.
I have tried using the ATI control panel to adjust my display, but there seems to be a problem entering it as an administrator.I can load the CCC just fine as a regular user, but when I try as an admin a terminal pops up, I type in my password, and nothing happens. I want to avoid trying to reinstall my display drivers or do anything drastic. In previous versions of linux I would just nano the Xorg.conf file and be done with it, but it seems ubuntu 10.04 LTS doesn't use Xorg, or at least not a Xorg.conf I am used to. I want to set the monitors at their native res and as independent displays, similar to what twin view did for me not to long ago.

I just got a new vVidia card for its HDMI capability for my mediacenter and installed the nvidia drivers suggested by the hardware managers.
Right now im connected to a VGA input on a sharp TV, this card/driver like my previous embedded intel card/driver can't make heads or tails of this TV. Intel called it "unknown' nvidia thinks its a CRT (/laugh at a 42'' CRT) so the resolutions it sticks me with are laughable.
Before i used to use xrandr to add a 1600x1400 resolution (though my goal is 1960x1080, full 1080p, i just cant run that through a VGA input) and all was... acceptable.
Now i can no longer do this, since nvidai drivers seem to dominate my attempts. I have gathered i should be able to alter my xorg.conf (which i used to not have, this machine started at 9.10 which is trying to get away from that file) to support som additional resolutions. But i swear i am all thumbs when it comes to touching that file... it always ends with a command line crawl to revert to my backup
SO, anyone know what needs to be altered with this file OR any other method i might try?
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder63) Fri Aug 14 17:54:58 PDT 2009
