i'm trying to get this to run at 1400x1050 (native lcd resolution)

my chipset is seens as follows

[root@localhost ~]# lspci
00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Proces sor to DRAM Controller (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Exp ress Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Gr aphics Controller (rev 03)

00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d3)


and my laptop (a Dell Latitude D610) cannot display the correct resolution in Fedora Core Release 5 (it should be 1400x1050 and thats what i told xorg to run at, but it displays at 1024x768 and that looks out of focus)

so i'm trying out this vbios hack for intel 9xx chipsets http://www.geocities.com/stomljen/

read the readme and did as required and strangely it reports the following vbios modes

[root@localhost 915resolution-0.5.2]# 915resolution -l
Intel 800/900 Series VBIOS Hack : version 0.5.2

Chipset: 915GM
BIOS: TYPE 1
Mode Table Offset: $C0000 + $269
Mode Table Entries: 36

Mode 30 : 640x480, 8 bits/pixel
Mode 32 : 800x600, 8 bits/pixel
Mode 34 : 1024x768, 8 bits/pixel
Mode 38 : 1280x1024, 8 bits/pixel
Mode 3a : 1600x1200, 8 bits/pixel
Mode 3c : 1920x1440, 8 bits/pixel
Mode 41 : 640x480, 16 bits/pixel
Mode 43 : 800x600, 16 bits/pixel
Mode 45 : 1024x768, 16 bits/pixel
Mode 49 : 1280x1024, 16 bits/pixel
Mode 4b : 1600x1200, 16 bits/pixel
Mode 4d : 1920x1440, 16 bits/pixel
Mode 50 : 640x480, 32 bits/pixel
Mode 52 : 800x600, 32 bits/pixel
Mode 54 : 1024x768, 32 bits/pixel
Mode 58 : 1280x1024, 32 bits/pixel
Mode 5a : 1600x1200, 32 bits/pixel
Mode 5c : 1920x1440, 32 bits/pixel
[root@localhost 915resolution-0.5.2]#

why isn't 1400x1050 listed ???
anyway...

to try and force it i tried the following:-

[root@localhost 915resolution-0.5.2]# 915resolution 4b 1400 1050
Intel 800/900 Series VBIOS Hack : version 0.5.2

Chipset: 915GM
BIOS: TYPE 1
Mode Table Offset: $C0000 + $269
Mode Table Entries: 36

Patch mode 4b to resolution 1400x1050 complete

and restarted X

(ctrl_alt_backspace)

guess what happened ? it WORKED !!! kudos to the dude who wrote this !
