OpenSUSE Install :: Can't Increase Resolution Than At Least Stretch The Screen To Full Screen?

Aug 27, 2011

I recently upgraded my graphics card from a Geforce 7600GS to a Gefore 560Ti. And while most things are normal, during boot up my screen isn't "full screen" until X is started, after which everything else is fine. Essentially, all display, the grub menu, the splash screen, console text, etc, is within a box on the screen, with 2" on the left and right, and 1" top and bottom of empty blackness.

From what I understand, this is because the framebuffer is using the wrong resolution, but the maximum resolution that hwinfo --framebuffer returns is 1280x1024 (which I am already using "0x031a".) (My monitors is natively 1920x1080) Is it possible to do something about this? If not increase resolution than at least stretch the screen to full screen?

sudo /usr/sbin/hwinfo --framebuffer
02: None 00.0: 11001 VESA Framebuffer
[Created at bios.459]
Unique ID: rdCR.GGyCBArXznD
Hardware Class: framebuffer
Model: "NVIDIA GF104B Board - 10400050"

General :: CentOS 5.4 Screen Resolution?

Feb 1, 2010

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)

Hardware :: CentOS 5.2, SIS661FX Screen Resolution?

Apr 9, 2009

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:


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 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.

CentOS 5 :: Aspire One Screen Resolution Stuck On 800x600?

Mar 31, 2011

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.

CentOS 5 :: Increase The Size Of The /tmp Directory ?

Nov 10, 2009

We have a problem where there is not enough space in our /tmp partition. We are trying for fix our mysql database, and keep running in to the space issue... the error we are getting says:

myisamchk: Disk is full writing '/tmp/STGL3SGd' (Errcode: 28). Waiting for someone to free space... (Expect up to 60 secs delay for server to continue after freeing disk space)

Our /tmp partition is current set at 485M, but it is not large enough to handle the database fix...

Does anyone know of a work around - perhaps to assign different directory for the temp files?
