Ubuntu Multimedia :: How To Force The Screen Resolution
Dec 16, 2010
I have my Xubuntu box connected to a 1920x1200 LCD monitor via a KVM switch. If the KVM is set to the Xubuntu box when I boot, all's well, but if the KVM is set to the other machine, Xubuntu boots into a 800x600 resolution. This behavior started with Maverick, when I was running Lucid. the correct resolution was set no matter the position of the KVM switch. Is there some place in Maverick that I need to set the resolution to 1920x1200 so it is set correctly regardless of the KVM?

I recently started using Ubuntu 11.04. Everything works fine with my monitor directly connected to the computer. I get a default screen resoluton of 1680 x 1050, which is just fine.
However, when I connect the screen through a video splitter to be able to use a beamer, the screen resolution defaults to 1024x768. Moreover, Ubuntu then detects an unknown monitor and I cannot select a higher resolution.
I searched for modifications of xrandr en xorg.conf but I have to admit I don't understand what I've read. So my question remains: how can I force Ubuntu 11.04 to start with a screen resololution of 1680 x 1050 (without first connecting monitor only, that is).
I hereby add some information I retrieved with the screen connected without the splitter, so you can see what hardware is involved.
Code:
dirk@LaboFysica:~$ xrandr
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192
VGA1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm
1680x1050 60.0*+
1280x1024 75.0 60.0

I wonder if anyone can help, I've got an annoying problem with an Acer Revo running Ubuntu 9.10 with the latest NVidia drivers. The Revo is connected to my TV via an amp by HDMI. The Revo didn't seem to like this, I'm assuming due to some handshaking issue with the HDMI which meant that no signal was being passed. Therefore, in Xorg.conf I have used
Code:
Option"UseEDID" "False" This makes the a picture appear but the highest resolution available is 640x480 (if I connect directly to my TV and comment out the "UseEDID" line the resolution is the proper 1920x1080).I have tried editing xorg.conf (the file is posted at the bottom) to force 1920x1080 resolution but nothing seems to work.
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Sun Feb 1 20:21:04 UTC 2009
Section "ServerLayout"

I have CeontOS machines connected to LCD via KVM which causes failure to properly detect screen resolution and I'm stuck with 800x600 until I reset X server with the LCD connected directly to the PC. How can I enforce higher screen resolutions?
EDIT: I followed the advise and left only one resolution in my xorg.conf but it didn't help.

I started using Ubuntu 11.04 today.
Everything works fine with my monitor directly connected to the computer. I get a default screen resoluton of 1600 x 1280, which is just fine.
However, when I connect the screen through a video splitter to be able to use a beamer, the screen resolution defaults to 1024x768. Moreover, Ubuntu then detects an unknown monitor.
I recall that I have solved this problem before with an older version of Ubuntu.
Now it seems that there is no xorg.conf anymore so I don't know what to do.
How can I force Ubuntu 11.04 to start with a screen resololution of 1600 x 1280.

I am trying to force a resolution (800x600) through xorg.conf. How to do that? The story is the following. I am trying to play a game (theocracy) on my toshiba nb100 (max resolution (1024x600) however the game supports only 800x600 resolution. To play I am using xgame [URL] which has the option to use a separate xorg.conf file to run the game. Even though I created a new xorg.conf1 file which only contains in its "screen" section Modes "800x600" notwithstanding the new screen, with the game is set to 1024x600. How to force 800x600 through the xorg.conf.

I'm having problems adjusting my screen resolution. I'm using Nvidia Geforce FX5300 video card and Samsung T220P LCD screen with resolution of 1920x1200. After installing the Nvidia driver I went to system -> preferences -> display in order to change the resolution to 1920x1200. Unfortunately, the available resolutions were only 640x480 and 320x240. I tried to set the resolution manually, using the advanced button, but when I did this everything was extremely big on my screen.

I can't increase my screen resolution to higher than 800x600. In Windows I have a 1024x768 resolution. This is my xorg.conf file
Code:
# xorg.conf (X.Org X Window System server configuration file)

# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

I know this is probably a stupid question , but I started using Ubuntu 11.04 .
My screen resolution on windows was 1600x900
But on ubuntu (even after installing proprietary drivers) the highest I can get is 1024x768 .
I tried using xandr but couldn't work it out .
My xandr info
When i tried adding a new mode using the command
I got the following error
Now I'm not sure what VGA refers to , but Im using a vga port to connect my monitor
Also I'm using only one monitor.

I upgraded from 9.04 to 10.04.1 so I am still using legacy grub.Anyway, I noticed with the update that the console is using the framebuffer and using VESA for high resolutions.I really don't like or want this feature. So I added vga=0 to get 80x25 and it works initially but just when the X server is running (Xubuntu in my case) I can see how the console switches to a high resolution again. After this, if I go to a console, lets say tty1, it is using again a high resolution instead of 80x25 (VGA). Is there a way to force the consoles to be in a lower resolution and keep it that way? It used to work fine in ubuntu 8.xx and 9.xx

Does anyone know where to manually set screen resolution in the new 10.4 beta? Used to be in xorg.conf, but it appears that it doesn't exist in this release.

My screen resolution keeps reverting back to the default resolution 800x600. I'm using ubuntu 10.04, but had the same problem on 9.10 on my Acer Revo r3600 ION. I am able to change the resolution to 1280x1024 but have to do it by the nVidia configuration tool. The tool then allows me to 'Save to X Configuration'which it appears to have done successfully.See the sections from my 'etcx11xorg.conf' file. This is the state of the file after a reboot by the way.how I can get my desired resolution to persist after I reboot?

I installed 10.04 on my former windows box last night, and I seem to be stuck at a screen resolution of 1024x768. I have a Geforce 7600 GT graphics card, and I installed current drivers via the hardware drivers option. I can't go above this resolution in the nvidia x-server settings, and even xrandr says the highest resolution I can use is 1024x768. What is up with that, and how can I change it?

I have been arguing with my acer aspire one laptop since I bought it in terms of the screen resolution and have never been able to solve the problem, although I seem to be getting close. I just updated to 10.04 (the netbook remix).I have been following the instructions for how to fix it here. The result was this:
Code:
liz@Pippin:~$ cvt 1366 768
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz

I'm trying to change the output resolution of a HTPC that's connected to a 720p plasma from (an auto set) 1024x768 to 1280x720 so that the output is the correct 16:9 ratio for the plasma.The HTPC is running Ubuntu 11.04 with a GeForce 7600GT and is connected via VGA cable to the plasma. The plasma automatically detects the PC input as XGA.
The worst effect of this is 16:9 media (video clips etc) looks really stretched out with the letterbox bars on the top and bottom and icons in general don't look square.Nvidia driver has been activated via Additional Drivers but the message reads;
Quote:
The driver is active but not in use"
Any ideas what that means? Should I be looking for a way to disable whatever the Ubuntu driver is so the proprietry one is in use?Under nVidia Xserver settings I don't have an option for a 1280x720 resolution, the next closest resolution for 16:9 is 1360x768 but then portions of the output are no longer visible on the plasma.Could it be as simple as using the DVI output (not the VGA) from the graphics card to the plasma to get a correct reading of the input. Still, I wouldn't have a setting for 1280x720

After upgrading to 11.04, my screen resolution was reset to 1024x768. As the native resolution for my monitor is 1920x1080, I went to reset that. The resolution didn't exist in the Monitors applications, so I did the following:
Code:
kane@Griffin:~$ cvt 1920 1080 60
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
[Code].....
The monitor adjust, but most of the screen shows tearing and doesn't update correctly. Hard to explain, so I attached a screenshot at 1024x768, working normally, and 1920x1080, fubar. I've cropped these images to get them to fit the forum limitations, but they still show the issue.
My monitor is an LG Flatron W2253TQ, my graphics card is an ATI Radeon HD 4650, although the manufacturer is Biostar. I'm using the default free drivers.

My monitor's dvi jack is damaged so my nvidia geforce 210 does not recognise the supported resolutions correctly.
result: while it actually can support upto 1440x900, the highest available resolution is 1360x768.
While on windows, i used the nvidia utility to add the custom resolution and everything was nice.
On ubuntu 10.04, i haven't found a way to do that yet. yes, i searched forums, tried a couple of things with the xorg.conf file and lxrandr, etc. but to no avail.
I did manage to get the resolution listed in ubuntu's own display manager, and it shows 1440x900, but it doesn't apply when i hit 'apply'.
The nvidia settings manager does not show the resolution.

I just changed the desktop on my thinkpad from awesome to i3. And now I have some very strange issues with the screen resolution. Because at home I use this x60 thinkpad on a dockingstation and a 19" display. As long as I used Awesome as my Desktop, the display manager as well as the desktop itself could handle the different screen resolution depending on if I'm out with just my 12" on my thinkpad or with the much bigger screen on my home 19" display.
I can understand that i3 maybe cannot handle this alone and I need xrandx to enforce the screen resolution. But why is the display manager (lightdm) also affected by this change? What is so different that even the DM cannot find the proper screen resolution?

I'm running debian lenny and want to change the screen resolution from 640x480 to 1024x768. I'm using a nVidia Geforce FX 5800 and I installed the additional nvidia drivers with the help of this tutorial [URL]. Here is my xorg.conf

Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "de"

When I try to change the screen resolution via the gnome menu I just can choose the 640x480 resolution and 50Hz refresh rate.

Just got an HP dv6-2150 laptop. Dual boot with Windows 7 and 9.04 (9.10 will not work but that's a different story). The screen resolution is too low and is set at the highest option available (1024x768 which is a 4:3 aspect ratio). The HP uses the new Intel i3-330m chipset with on-board Intel HD graphics. The system is capable of 1366x768 resolution (16:9) - so how do I get it there? xorg.conf looks real generic - nothing specific to Intel.

Since I upgraded to 9.04 a while back I have had this annoying screen resolution issue. Every time I log into my Ubuntu system the screen resolution defaults to 1280x1024. My preferred desktop resolution is normally set at 1680x1050. So each time I log in I have to open the Nvidia control panel and manually set the screen resolution to 1680x1050. Even after logging out it will still go right back to 1280x1024 when I log back in.
But the funny this is I am almost positive the login screen resolution is 1680x1050 because the picture is crisp unlike the blurry and distorted picture at 1028x1024. I have tried everything from manually editing the x.org conf file to running the Nvidia control panel as root. Nothing saves my preferred resolution of 1680x1050. My Nvidia driver is version 190.42 and Ubuntu version is 9.04. The monitor is an ASUS VW192T+ which is detected by the Nvidia driver.

I'm trying to get my screen resolution set in Mythbuntu 9.10, but there is no xorg.conf on my system! I'm trying to figure out what to do (the xfce tool on mythbuntu doesn't offer the correct resolution, and I'm not even sure what driver I'm using). I've seen other threads saying to run nvidia-setup or somesuch. I assume the appropriate tool in my case would be aticonfig (I saw that elsewhere too) as I'm using an ATI Radeon 9600XT, but that tool says:
Code:
aticonfig: No supported adapters detected

I recently bought a 37" Vizio M370NV HDTV and connected it to my Kubuntu 10.10 desktop.Currently my resolution is 1280x1024, so there is black bars on the side of my screen. I want my resolution to be 1920x1080, which is what the TV/monitor says is it's primary resolution. However, when I set that resolution in nvidia-settings, my screen scrolls up. By that I mean that my screen keeps moving up my monitor and appearing at the bottom.

I have a dell studio hybrid PC which I am hooking up to my TCL brand 40" LCD TV to use as a media center pc. The problem I am having is that I can't get the TV's native 1920x1080 resolution to display properly. The rendered desktop doesn't quite fit in the screen (I think its the top and bottom edges that are cut off) so for example the menu bar at the top is completely off the screen.
1680x1050 works fine in the sense that it fits the full desktop to the screen size, but its not the native res. In the resolution changer utility, it recognizes that my TV is a TCL brand but mentions 36 in the model name (the TV I have has 40 in the model name to denote 40") so I think Ubuntu is recognizing the wrong size TV. How can I finagle the screen settings to make the 1920x1080 fit properly on my monitor? Or get Ubuntu to correctly recognize my TV? My TV is a no-name brand so its hard to find info on it or others setting up linux with it.
