[Debian 3.1]-Gnome Screen Resolution and USB flashdisks...

Hi to all!

Straight to the problems...

1) Screen Resolution in Gnome:

Can't get it to work at 1280x1024 or 1024x768 that i'm interested.
I have tried:

a. Editing /etc/X11/XF86Config-4
b. Running "dpkg-reconfigure xserver-xfree86"

In the menu Applications->Desktop Preferences->Screen Resolution there are - whatever i do - two options: 640x480 and 800x600

I've searched a lot but nothing seems to fix this problem.

2) USB flashdisks:

When i plug my flashdisk in the port nothing seems to happen. I've used Suse and CentOS and both when i plug in the flashdisk, a shortcut on desktop appears to browse contents.

Some hw conf that might be helpful:
m/b: Asus Cusi-m (vga onboard sis630)

Needless to say, i've checked that my system hardware works perfectly. It is tested in many other linux distros.

Thank you very much and i hope that someone will solve my problems :-)

I can help you solve the first problem.
It is probably the refresh rate of the monitor that limits your resolution.
You can edit the file /etc/X11/XF86Config-4.
Find 'Section "Monitor"'
You need to edit:
HorizSync 30.0 - 70.0
VertRefresh 50 - 90
These are my settings. You may be able to use higher or lower. Beware that a too high refresh rate and HorizSync could fry your monitor.

Try what works for you.

Backup the file before you save your changes!
Then you need to restart X. Logout and press Ctr-Alt-Backspace.
Good luck!

Regarding the second problem - make sure you are running kernel version 2.6 (not 2.4) and have packages udev, hotplug, gnome-volume-manager installed.
After you upgrade to 2.6 kernel and install these packages, your USB key will start appearing on your desktop when you plug it in.

When you plug the flash drive in, execute "dmesg" and see if it recognised. Also try
cat /proc/scsi/scsi
Assuming that the correct modules are loaded (See above post), it will probably be assigned to /dev/sda.

Make sure the directory /media/usb exists

Then you should be able to mount it by:
mount -t fat32 /dev/sda /media/usb
I hope this helps

Thanks a lot!
Concerning the first problem, it was a little tricky: i have a sony SDM-HS73/P lcd monitor, which supports at max 1280x1024@60Hz. The max at all resolutions is 60Hz. I tested various V+H values and i finally made it work at 1024x768@60Hz.

About the flashdisk: when i plug it , its recognized (running dmesg - displays it), it says sthing about sda, but when i mount it, displays an error about the file system (it is formatted in fat32 though).
