855resolution says that my vbios supports 1280x1024 mode...what now?

Description Christopher Stender 2005-08-10 09:04:20 UTC 
My box is a Siemens SCENIC W620PC with an i915G chipset and a Siemens Scaleoview
19inch S19-1 TFT. YaST detects the graphic card and the screen correctly. It
recommends a 1280x1024 resolution by default, but X.Org and the framebuffer use
a 1024x786 resolution. After changing the vga value in grub.conf to "vga=0x31a",
grub won't start Linux before he get a correct resolution.

Your BIOS does not support the 1280x1024 resolution. Unfortunately the i810
driver needs the BIOS support. Try to use the 855resolution tool (same package
name) to workaround this.

Comment 5 Stefan Dirsch 2005-08-10 12:10:29 UTC 
Right, but the driver doesn't think so. :-(

855resolution:
--------------
Mode 38 : 1280x1024, 8 bits/pixel
Mode 49 : 1280x1024, 16 bits/pixel
Mode 58 : 1280x1024, 32 bits/pixel

i810 driver:
------------
Mode: 38 (0x0)
Mode: 49 (0x0)
Mode: 58 (0x0)
Comment 6 Matthias Hopf 2005-08-10 12:30:44 UTC 
As grub doesn't boot in 1280x1024 as well, I think that 855resolution is wrong
with its statement. I think seife packaged that tool. Adding him to CC just for
info.
Comment 7 Stefan Dirsch 2005-08-10 12:35:45 UTC 
No, it was me, who packages this tool. But you're right, it makes me wonder that
grub doesn't boot into 1280x1024. Anyway, you still can try to overwrite a mode,
which you don't need, with a 1280x1024 mode with 855resolution.
Comment 8 Christopher Stender 2005-08-10 12:42:20 UTC 
Already tested ... it doesn't work.
Comment 9 Stefan Dirsch 2005-08-10 12:45:48 UTC 
Ok. It was worth a try. Maybe your vendor provides a BIOS update ...
Comment 10 Stefan Dirsch 2005-08-10 13:39:26 UTC 
Unfortunately this is sth., which we currently cannot fix (on Linux). Try to
complain loudly to your vendor to fix the BIOS and provide a 1280x1024 modus.
Comment 11 Stefan Dirsch 2005-08-11 03:10:29 UTC 
One last try. Make sure you use a 32bit mode for overwriting, which is 
detected valid by the driver, so use one of these for 855resolution: 
    
*Mode: 50 (640x480)    
*Mode: 52 (800x600)    
*Mode: 54 (1024x768)    
    
e.g. try "855resolution 54 1280 1024"
Comment 12 Christopher Stender 2005-08-11 13:14:41 UTC 
Already tested - it doesn't work. I will talk with Fujitsu Siemens and ask for a
correct BIOS. Thanks for your efforts.

I'm really sorry. Finally resolving as WONTFIX.
