Re: No 1028x786 resolution on HP M50 Monitor On Sarge

Thanks to all for the very quick response and for copying me direct. Noticed you didn't copy list so am taking the liberty and doing so. I'm using this response to 
reply to all for efficiency but all responses have a reply.  See below.

Only the 800x600 and 640x480 are available while previously 1028x786 was functional and I could switch to it with cntrl ++. The higher resolution had been available on both woody and sarge kernels(stock). 

what kernel are you currently running and did you install with apt or
compile it yourself?
I'm using stock 2.6.8-2-686 and have 2.4.18-bf2.4 as backup. Installed with apt 
and I don't compile being a newbie.
I have ran dpkg --reconfigure and wajig reconfigure xserver-xfree86 and always select the 1028x786 max resolution. I've tried modprobe r128 and get a message that file not found or doesn't exist but it does and modprobe gives the same message with or without the full path name. 

can you paste the complete message? (if you have no X windows to paste
from maybe ssh in from another machine with X)

ChatagnierL-Home:/etc/devfs# modprobe r128.ko
FATAL: Module r128.ko not found.

PS-the above path is taken right out of the locate output after being updated. 


what card is this? ati rage 128? (im not familiar with ati)
It's a module that I believe must be loaded for dri and the higher resolutions to work. Read it somewhere while googling but don't remember where. I'll stand corrected if I'm wrong. 
My video card is ATI 3D Rage Pro AGP 1X/ 2X rev 5c
I'm somewhat of a newbie having been with Debian and linux for about 6 months and don't know what else to do. The pertinent section of my XFConfig-4 file is copied below for referene and would be glad to provide any other needed date:

If you are sure the horizontal andvertical refreshes are correct,
(check the manufactures website for your monitor) then do:

HP M50 manual gives: line Horizontal freq 30-54 KHtz
                                      Raster Vertical freq 50-100 Htz
Also, max frequency for 1024x786 of 60Htz, 800x600 of 85 Htz and 640x480 of 85 Htz. Note that all resolutions were once working on both woody and sarge set up using the simple selection when configuring xserver-xfree86. Debconf or dpkg actually selected the frequencies. 


cp -iv /etc/X11/XF86config /etc/X11/XF86config.backup

and then edit the file directly, adding the mode you want.
for example:
SubSection "Display" Depth 16 Modes "1028x786" "800x600" "640x480" EndSubSection 
You can also install modconf, which is a curses based gui module
loader to make things a little easier. 
also look here http://www.xfree86.org/3.3.6/r128.html for any tips.
good luck!
To: cmatheson3@yahoo.com, Yes, I'm aware and at one time when all resolutions were working it showed up in the config file. Have been a little afraid to manually edit the file do to the warnings at the beginning of the file. I've always did a dpkg or wajig reconfigure selecting simple monitor configuration and sellecting the 1028x786 resolution on the popup screen if it wasn't already selected.
To: tcpankon@gmail.com, Same as above but will now try it as it has been done before.
To: All, After modifying XF86Config-4 and rebooting, I still seem to have only 2 resolution using cntrl-alt-++ but the screen looks to have a finer grain like the 1024x786 resolution. Is there a way to explicitly tell what screen resolution is running? I should know how, but not on Debian. 
Thanks to all and I will review the above link,
Leonard
