Low Screen resolution

[James420]

I have an issue with a IBM Thinkpad 600 that had no issues with FC2, now I am running FC3 and the laptop will not run anything higher the 800x600.

I tried going in a root user into the /etc/x11/xorg.conf file and it shows that it will go to 1024x768. Then lower down it shows "600x400" "800x600" "1024x768"


but when I go to change the resolution, it only gives the options of 600x400 and 800x600


any ideas?

Look in /var/log/Xorg.0.log and see if all the modes you asked for were accepted.

Go up a bit in the xorg.conf file and look at the

HorizSync

and

VertRefresh

lines inside your "Monitor" section. I changed mine to this

HorizSync 31.5 - 94.0
VertRefresh 50.0 - 90.0

and 1024x768 was suddenly perfectly fine.

Try running system-config-display and setting your LCD display type and desired resolution from there. I forgot to add...Do this as root from a terminal, not from the applications menu.

I'll get it right eventually! Set your LCD type to generic and the desired resolution.

I've tried everything you guys have given me, and still nothing. All the changes have worked and were saved.

here is what I have it set at:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "LCD Panel 1020x760"
HorizSync 31.5 - 94.0
VertRefresh 50.0 - 90.0
Option "dpms"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480" "1024x768"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "800x600" "640x480" "1024x768"
EndSubSection
EndSection

Thank you for the link, worked perfect, as I was having the same issue after. I got it to run, but I would have to scroll the "desktop" and run the xvidtune and fixed it. Thank you for the help.
