Skewed screen - Mobility Radeon X1450 with vesa (only feisty, edgy; dapper is ok)

[Boris Dušek]

Binary package hint: xserver-xorg

Hello,

I tried Feisty Herd 2 (as live CD), and it has the same problem as Edgy Eft:
The screen in graphical environment is skewed; autodetection uses the vesa driver.

This is a regression from Dapper - there it worked fine.
I have some photos of the problem at flickr:http://www.flickr.com/photos/76746644@N00/378412923/http://www.flickr.com/photos/76746644@N00/378411688/

My screen is 1400x1050, Graphics card is Mobility Radeon X1450, laptop is ASUS F2JE.

I tried to follow instructions at DebuggingXAutoconfiguration, I will attach the outputs soon.
But what surprises me is that the xorg.conf for Dapper and Feisty is the same, but there is no problem in Dapper.

I tried to reconfigure xserver-xorg, and the screen was no longer skewed, but, the resolution was 1024x768, which is not desirable. (This happened even though only 1400x1050 was set in the config.)
The only difference between Dapper's, skewed and low-resolution xorg.conf is always the HorizSync and VertRefresh parameters.

The problem is present no matter if I choose default boot options, or if I remove "quiet splash" and add "vga=771" (or "vga=791").

I will be glad if I can help to resolve this issue by providing additional information.

Thanks,
Boris Dušek

discover --disable=parallel,serial,usb,ide,scsi,pcmcia

Output is empty.

This is for the reconfigured server, where the screen is not skewed, but resolution is only 1024x768

Still present in Herd 5 (Feisty).

Wow, in Feisty Beta it's fixed. However, part of boot is displayed in text mode, I don't know if this is intentional.

Thanks for testing! The new vesa driver did the trick, I think.

[Boris Dušek (dusek)]

btw., why fglrx (ATI's binary driver) is not used for my card when we have the restricted driver manager?

sadly, X crashes on start with Feisty RC
here is diff between xorg.conf from beta to RC:
< Modes "1400x1050" "(pitch" "1400)"
---
> Modes "1024x768" "800x600" "640x480"

To clarify, in Beta, where it was working, the line with "(pitch" was used. In RC, the line where "1400x1050" resolution was missing was used
