Red Hat Bugzilla – Bug 82364
X i815 fails in 16-bit color depth when switching VCs
Last modified: 2007-04-18 12:50:11 EDT
Fresh installs of RHL 8.0, fully updated
These machines (Gateway e-3400s) have i815 video chipsets. They fail ~50% of the
time when switching from a running 16-bit 1024x768 X session to a text VC; they
switch, but when you switch back to X, the X server has died
Switching to 24-bit 1024x768 seems to prevent this
How about phoebe2?
phoebe 2 does seem to fix that
w/ both phoebe2 and 8, running multiple X servers is possible in 24-bit mode but
not in 16-bit mode (dies with agpgart errors when starting the second X). That's
probably a hardware / kernel issue, though, I would think?
Running more than one X server simultaneously on a single video card
is not supported. It works rather flawlessly with many combinations
of hardware, but not with others. The failures tend to be video card
specific, or to be related to wether a given card is primary or
secondary (such as 3Dfx hardware), or it can be some other combination
It is generally rather hardware specific. Considering the number of
users who actually use multiple X servers simultaneously, compared
to the number of users who have reported inability to get just a single
head up and running and video working, bug troubleshooting/debugging
prioritizaiton must be assigned to getting hardware working for more
people who it does not, so special-case scenarios like multiple
X servers on one box, which are much rarer, take very low priority.
Rather than leave them sit at low priority, and most likely never get
any attention due to there always being higher priority bugs to fix,
my best recommendation would be to report issues like that directly
to firstname.lastname@example.org mailing list.
I'd rather be honest with you than leave such a bug open for 2 years and
not ever touch it simply due to prioritization.
Since you've indicated phoebe 2 resolves the originally reported issue,
