Display will not hold 1280 x 1024 on Boot, through primary screen

cherock1254 · June 15, 2011, 3:59am

Display will not hold 1280 x 1024 dpi. Smaller than normal on splash screen, then full screen at 800 x 600 for login page and primary pages. I go to the Display manager under tools “Configure Desktop” change it to 1280 x 1024. it prompts to accept I do, then hit the apply button and changes to correct screen. When I close down goes back to previous settings. Can’t figure out why they are not holding. Any ideas where to look to fix?

I also don’t have VGA mode anymore. The Displays are only one for this machine. I have DVI-1-1 Disabled and DVI-1-2 which defaults to 1024 x764 instead of the 1280 x 1024 (Auto) that shows in the drop down box. I believe I still have a VGA cable to the card too. ODD, ODD, ODD… Wondering if this might be the problem.

Which desktop are you using?
What graphics hardware (and driver) do you have?

/usr/sbin/hwinfo --gfxcard

Ok, it appears you’re using the open-source nouveau driver, is that correct? You may want to try installing the nvidia driver instead. (It can cope better with different display devices).

SDB:NVIDIA drivers - openSUSE

However, if you want to stay with the nouveau driver, then maybe a minimal config adjustment will work. First adjust /etc/X11/xorg.conf.d/50-monitor.conf (by uncommenting the horizontal sync and vertical refresh timings). You’ll need to be root for this.

Section "Monitor"
  Identifier "Default Monitor"

  ## If your monitor doesn't support DDC you may override the
  ## defaults here
  HorizSync 28-85
  VertRefresh 50-100

  ## Add your mode lines here, use e.g the cvt tool

EndSection

Then edit /etc/X11/xorg.conf.d/50-screen.conf like this

Section "Screen"
Identifier "Default Screen"
Device "Default Device"
Monitor "Default Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024"
EndSubSection
EndSection

Save the changes, and restart the X-sever when done. See if that helps.

Now I am showing fbdev ? What is this now.? Also, can’t boot to my normal OpenSuse Graphical Window, it blanks out the screen like it is in Power Saver Mode. Have to use Failsafe to load and operate. I have the original Nvidia Drivers, but I am not sure if I should try to load or really where to start. They are Window Drivers (Original Drivers) dvd.

Ok, the nouveau driver is a basic open source driver that may not give you the results you’d like, and seems to have trouble coping with certain display modes. You can safely remove the configuration changes you made, or even remove the complete entries if desired. (Manual configuration is not usually required when automatic detection works).

I would try installing the proprietary nvidia drivers from

SDB:NVIDIA drivers - openSUSE

The windows drivers are for exactly that: Windoze. Install the Linux drivers.
