General :: Force Screen Resolution On CentOS Machine?
Jun 2, 2010
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 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.

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 have been searching for the past few days on how to do this i have found many articles all telling me slightly different ways of doing so but none have worked. the monitor i am using displays at 1680x1050@60Hz however most access will be from a laptop running at 1366x768 through VNC i have the VNC working thats not a problem my current problem is that when i turn it on the screen defaults to 1600x1200@60Hz when i go to System>Preferences>Screen Resolution the options i get are 1600x1200, 1280x1200,1024x768, 800x600, 640x480 however when i change to something other than 1600x1200 the refresh rate changes to 85Hz and cannot be displayed by my monitor so i have to wait for it to default back, not that i want to change it to any of those in the long term /etc/X11/xorg.conf looks like this (i have only edited the Modes line)
I am running Debian on a g3 mac and when I set the screen resolution to 1024 by 768 I cannot see everything, for instance the scroll bar on iceweasal is hidden, so I switched the resolution to 800 by 600 and then i load up evolution and find that the forward button isn't visible, is there a way to get a custom resolution that works with everything
I have a centos 5.5 server, without a monitor connected to it.Sometime i need to connect to it with VNC, but maximum resolution is 800x600.How can i increase it at least 1024x748 ??I tried in system-config-display changing the monitor to a generic CRT 1024x768, and rebooted.But only allowed resolutions are 800x600 and 640x480.
How to change the welcome screen resolution? (Where you input the username and password) I use NVIDIA driver which download from its official web site. After reboot, the welcome screen out of bottom.Change session, language and restart computer menu not in the screen. Is there a way to set the welcome screen resolution? or how can I fix it?
Loaded Cent O/S on VMWare Workstation to begin learning for enterprise role.. The largest screen resolution is 800x600. Is this the max or how can I change it to a larger res.?
OK, I have Googled to the end of the Earth and am starting to got nuts! I cannot seem to get my onboard graphics to display a resolution greater than 800x600. As mentioned in the title, I am using CentOS 5.2 and the graphics chip is a SIS 661FX. I have checked that the latest driver is installed, changed the /etc/X11/xorg.conf file to include:
[Code]..
Now, if I restart the system, on occasion I have seen the correct resolution (1204x768), but if I check in "system, administration, display", I only see 2 options (800x600 and 600x480). The next time I restart it goes back to 800x600.
I should add that I have tried several options for modeline (present and absent) and modes in the xorg.conf. The automatically-generated xorg.conf file (after installation) has detected the "sis" driver.
I am running Windows 7 inside KVM on Cent OS 5.6. how do you change the screen size of the Windows 7 KVM. It is about a third of the size of the current screen resolution.
New install of 5.4 and I have a dell S1909W display that runs 1440x900. I don't run a windowed environment and only use CLI. I am only getting 25 lines per screen with huge text and I need to set the resolution so I can actually work :) I tried adding vga=866 to my /boot/grub/menu.lst file at the end of the kernel line but nothing changes after reboot.
I used to use Linux a long time ago and remember there was a way in the startup script to change the video resolution from 80x25 to high resolution line 50 lines mode. I can't seem to find were to do that any more. I have been reading posts and etc and everything is about changing resolution in X-Windows. how to change the default screen outside of X-Windows>
My monitor is an old, low-res (800x600 resolution) flatscreen, and the loader keeps trying to set it for 1024x768.the initial setup and package selection screens ran fine. it was only after rebooting to the "Welcome" screen that the problems started. I found the "resolution= (800x600 for me) under "additional boot options", but I don't know how to use it.
I've installed CentOS 5.5 on my Acer Aspire One D150. It uses the Intel integrated graphics chip GM945 which isn't supported "out of the box" by CentOS. My screen resolution has defaulted to 800x600, but it should be 1024x600. tried xrandr, and editing the xorg.conf file, and now have gone down the rabbit hole of trying to install xf86-video-intel and its associated dependencies (nested like Russian matryoshka dolls). I'm at the point of trying to install xorg-server, but am getting hung up by its dependencies on xproto and fontsproto, despite having installed them.
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 have two monitors attached to my video card. Primary monitor has a resolution equal to 1280x1024 and second has 1920x1200. My gdm login screen always appears on the second monitor even if it is switched off. My question is how to force gdm to show login screen always on primary monitor with resolution 1280x1024? I use Ubuntu 10.04.Now I'm ready to modify gdm sources if there is no such option in configuration files.
When I run a script with nohup, the output is forced to the out.log file by default; is there a way to force the output to the screen instead of the file? I need to be able to see when my script gives me a "process started" message, and I don't want to clog up the system with log files.
Unfortunately my experience in the Unix* based world up to this point has only been using web servers and administrating them, no GUI experience of any kind so I am completely unfamiliar with the setup and entire usage of Xorg or any other Window manager at this point. The issue I am having is with the screen resolutions I am being allowed to chose for my Dell Studio 1535 running Fedora Core 13 and the KDE 4 desktop GUI, thus my issue since I am not really familiar with how to run a Unix* based GUI in the first place.
The basic information, if there is more needed just advise what and what command gathers that info (or what conf/log I should look into in order to find it). Laptop is a Dell Studio 1535 Video is the Mobile Intel GMA X3100 ATI Radeon HD 3200 Graphics. LCD interface is the LVDS.
So far it seems to give me modes for 1024x768 and on down, nothing above this. I believe I am supposed to use the radeon driver being that is the type of card it is but every time I change the xorg.conf file to use this instead of vesa the system wont get past the loading screen anymore upon reboot and nor can I seem to find a way to bring up a command line so I can hit up the Xorg.0.log to see what is wrong or change the xorg.conf file back to the original driver it had listed.
I am going to assume this is a missing driver or something else it hangs on but without being able to get access back to the system and having to rebuild it again (re-install via live CD) I am basically out of luck at this time. Sorry for the rather poor post but I do hope to receive some basic directions on where to go from here with this issue
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
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 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.
In general CentOS search automatically after startup for available software updates.Then after some (~20-30) minutes an icon appears in the toolbar which the user can click and install the updates.How can I manually speed up/trigger IMMEDIATELY the search for updates (without waiting for the built-in search)?
I've tried Kubuntu, but I don't get any higher screen resolution than 640*480. The graphics adapter that seems to get me in trouble is an Intel based one.
I'm open to other OS'es that uses KDE -I just need to be able to use Kdenlive.
