I've entered this bug in the Ubuntu bugzilla already
but am getting desperate to fix the problem so am entering it here too.
When I try to start the xserver using the vesa driver on my toshiba R100 with
Trident CyberBlade XP4m32 graphics card, X takes up 100% of the CPU. The last
entry in Xorg.0.log is:
(II) VESA(0): Splitting WC range: base: 0xffffffff, size: 0x2000000
The logs and the lspci output are attached to the ubuntu bug.
I've searched google, and the xorg bugzilla extensively, but not found anything
The vesa driver does appear to work on Fedora core 6 (with the same version of
X: 7.1.1), so perhaps this is an issue with Ubuntu's packaging or upgrade
procedure. Still, I feel that X should give a meaningful error and abort rather
than hanging partway through.
Any suggestions about what to try would be much appreciated.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
I can confirm that the exact same bug occurs with the same laptop also under openSUSE 10.2 (X11 Version 188.8.131.522 (7.2.0 RC 2)); further details filed on the SUSE bug tracker:
This no longer seems to be an issue for the version of xorg that ships with Ubuntu Hardy:
X.Org X Server 184.108.40.206
