setting resolution correctly on Intel 9xx chipsets...


Recommended Posts

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)

00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Ex press Port 1 (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

Mode 32 : 800x600, 8 bits/pixel
Mode 34 : 1024x768, 8 bits/pixel
Mode 38 : 1280x1024, 8 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
