I have been wrestling with this problem for about 3 days now, so here I am asking for help. I just installed a G200 Dual Head video card, running Slack9.1 (doesn't matter much I guess). Anyway, I got "Dual Heads" up and running, but I get different resolutions on each monitor. I have my xorg.conf set for 1280x1024. I get it on one monitor, but on the second monitor I get 800x600. When I look in the Xorg.log, I see that it is indicating there is not sufficient memory to use the 1280x1024, therefore defaulting to 800x600. My question is.... Is the a formula to see what resolution would be supported given a specific bit depth, H & V freq, etc.... Ideally I would like to have 1280x1024 on both monitor, but will settle for less just as long as they are the same. BTW, I have 32MB video memory on the card.


Thanks for your help.....

If you set you color depth to 16 bit you should be just fine. You may also wan't to check your XF86Cofig file, and make sure that you have 1280x1024 for both moniters.

Thanks for your suggestions, but I THINK I already covered those bases... I am including a portion of my xorg.cong and the error I am getting...

(--) MGA(0): Virtual size is 1152x768 (pitch 1152)




I guess after looking at this, it may not be a memory issue.... Any thoughts....




Thanx,
Kiley

Sorry screwed up again..


here is the relevant xorg.conf section, I forgot a portion of it..

thanks for being patient with my mistakes

Of course it doesn't work, the lines are commented out!
Change this,
# Subsection "Display"
# Depth 8
# Modes "640x480" "800x600" "1024x768" "1280x1024"
# EndSubsection
# Subsection "Display"
# Depth 16
# Modes "1024x768" "800x600" "640x480"
# EndSubsection
Subsection "Display"
Depth 16


too this,

Subsection "Display"
Depth 16
Modes "1280x1024"
EndSubsection
EndSection

and it should work just fine.
Noah

Sorry for the confusion Noah, I noticed when I cut and pasted the 1st post I forgot a few lines, so I reposted it (see second post). You will notice I have a Depth 16 entry that is uncommented and it still does not work. Again sorry for the confusion. Please feel free to let me know if I am MORE confused than I think.
