Resolution Problems with i810 chipset in Debian Lenny

[GhostofSin]

Good evening, recently i upgrade from Debian Etch to Lenny and i have problems with the resolution, i only get 1024x768 and the monitor i have supports 2048x1024. When i used Debian Etch i didn't have this problems. This the xorg.conf file :

 /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

Hi !

Install 915resolution.

su
apt-get install 915resolution

Reboot machine.

After install 915resolution as root i typed :

# 915resolution -l ( ...this is the list that appeard..)

Intel 800/900 Series VBIOS Hack : version 0.5.3

Mode 5a : 1600x1200, 32 bits/pixel
Mode 5c : 1920x1440, 32 bits/pixel

I choosed the option MODE 4a 1600 1200 because according to the 915res' manual i must choos a resolution i wont use then i typed :

915resolution 4a 1280 1024 24 ( because i want a resolution of 1280x24 at 24 Color depth) and this is what it showed me :

Chipset 845G
BIOS : TYPE 3
Mode Table Offset : $C0000 +$4d2
Mode Table Entries : 25
Patch mode 4a to resolution 1280x1024 complete


Then i add this line to /etc/init.d/bootmisc.sh

/usr/sbin/915resolutio 1280 1024 24

The manual sasy i must do this to start this service every time y start the pc. Finally i add :


Option "ForceBIOS""1600x1200=1280x1024"


To the Section "Device" in the /etc/X11/xorg.conf file. I restarded and start the X window system ( Fluxbox ) but the problem stills there, can't get more resolution than 1024 x768 @75hz , am i missconfiguring anything ? What should i do ? thanks !

Check your Monitor's Manual and set supported HorizSync/VertRefresh rates.

Accidentally i was "playing" with the vertical sync. values, then i put one shorter than the one in the manual and all works !!! , then i uninstalled the 915resolution and all work also . I don't know the reason of this , but at least i found a solution that may help pthers, i may say that when i was in Debian Etch the vaules in teh Vert/Horz Sync where the values that the manual specifies. Thanks

Well Done ! 915resolution fixes Screen flickering and set Higher Resolutions which Intel Chipset doesn't support but Monitor does.
