Resolution above 800x600

  Date: Dec 13    Category: Unix / Linux / Ubuntu    Views: 372
  

I've installed Ubuntu 8.04 onto a Toshiba laptop:

- Satellite Pro 4600
- cpu: p3, 800 mhz
- 512 mb ram
- dvd rom.

Everything works except the screen resolution maximum setting is
800x600. The xorg.conf file seems to have no specific info on the
hardware, just defaults:

...
Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Synaptics Touchpad"
EndSection
...

Version 7.04 did not have this problem. All I want is to increase the
resolution to the screens full capacity. I think it 1024x768.

Could I take a snapshot of the 7.04 xorg.conf and replicate it here?

Does your laptop have an ATI or Nvidia video card?
If it does then when you install the proprietary hardware drivers for
either then you can fix the resolution.

I've downloaded SysInfo to identify the video card. It's a TRIDENT
MICROSYSTEMS CYBERBLADE/XP.

I ran Kubuntu 7.04 live cd. It uses a ´trident´ video driver and the
xorg.conf file has all the trident config info. I'm probably going to
try some cutting and pasting if I can find drivers.

I have the same computer with the same problem. I found the fix here

I believe the problem is the refresh rates (they need to be added) I
copied all the monitor and screen sections to my xorg.conf file and it
works just fine now.

your link for some reason didn't solve the problem but it showed
me how to overwrite the xorg.conf file which had me stumped.

What I did do was copy the monitor paragraphs that referred to the
monitor from a Kubuntu 7.04 Live CD bootup. After that, I had to
beboot and set the screen res from 800 to 1024 which was now
available. Here are the paragraphs I replaced:

# Section "Device"
# Identifier "Configured Video Device"
# EndSection
#
# Section "Monitor"
# Identifier "Configured Monitor"
# EndSection
#
# Section "Screen"
# Identifier "Default Screen"
# Monitor "Configured Monitor"
# Device "Configured Video Device"
# EndSection

Section "Device"
Identifier "Trident Microsystems CyberBlade/XP"
Driver "trident"
BusID "PCI:1:0:0"
EndSection

Section "Monitor"
