Screen Resolution Selection in Etch
|
|
|
| Just installed Etch (again) on another computer and an odd thing
happened.
The resolution was set to 640x480, and that is the only choice
(GNOME). I test a computer before install by running Knoppix, and it
detected the Voodoo 3 3dfx card and that the monitor could support
1600x1200 (Viewsonic 21" professional p225). So I was surprised that
the resolution was set so low, especially since this card is supported.
Unfortunately Debian can't seem to write to the floppy, USB device,
the FAT-16 second hard drive, or see the Windows network, so I made a
few notes about the Xorg.conf file.
Section "Module"
..."dri", "glx"
Section "Device"
Identifier "3Dfx Interactive, Inc. Voodoo 3"
Driver "tdfx"
Section "Monitor"
Identifier "P225"
Option "DPMS"
Section "Screen"
Identifier "Default Screen"
Device "3Dfx"
Monitor "P225"
Default Depth 16
SubSection "Display"
Depth 16
Modes {All common display resolutions)
Depth 24
Modes (All common display resolutions)
Would appreciate any help debugging the problem.
Dave,

What does /var/log/Xorg.0.log say?
You cant have "(All common display resolutions)" in your /etc/X11/
xorg.conf-file, as the X11-server doesn't understand that.
(That is, give us ALL relevant sections, not only parts of it).

Because I had to transcribe the contents of the Xorg file by hand (no
floppy, or LAN support yet) I generalized by saying "All common..."
The actual Modes are:
640×480
720×348
720×350
800×480
800×600
1024×768
1120×832
1152×864
1280×1024 <== resolution used under Knoppix and Windows
1366×768
1440×900
1400×1050
1600×1024
1680×1050
1600×1200
Thanks,
Dave

Ok, looks ok. Have you looked into /var/log/Xorg.0.log ? It might
give some clues.
You could compare that with what knoppix gives.
If you look what /var/log/syslog gives when you enter an USB memory
stick, what do you get?
A memory stick is used as an SCSI-device, so it's device should be
something like /dev/sda?
You could try to manually mount that device as root on /mnt or
something.
If you get errors about file system, try to specify it in the mount
command.
Good luck
