389992 - qm-centos5 needs to be in 32bpp display mode

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

qm-centos5 is right now running in 16bpp display mode.  It needs to be in 32bpp; this is the cause of the various reftest failures and the like.

(All our linux tinderboxen/testing boxen need to be in 32bpp.)

32bpp, really.  (Linux still has a packed-pixel 24bpp mode that's to be avoided like the plague.)

this should be fixed. Made the changes in xorg.conf and confirmed the settings were changed in Settings>Display (reported "millions" of colors).

Comment 3

[Rob Campbell [:rc] (:robcee)]

after messing around with this, finding the right place to put the args in for 32 bit display, I had to remove them again. See attachment for the vncserver log.

this is the server running in 32bpp.

whoops.. 24-bit depth, 32 bits per pixel.  So -depth 24 I think?  (It's confusing on linux because there's this old 24 bits/24 bpp mode that's packed-pixel RGBRGBRGB still around... and you definitely don't want that.)  I think -depth 32 there was trying to do something like 11/11/10, which, while cool, isn't quite supported :)

Comment 7

[Rob Campbell [:rc] (:robcee)]

hm, that might explain the yellow cursor color on the black background. Ok, I'll try -depth 24 when I can get a chance amongst all the checkins. It's been pretty steady all night and don't want to break the tree during freeze.

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

Well, should be very few checkins -- so now's probably the best time to break that specific machine.

Comment 9

[Rob Campbell [:rc] (:robcee)]

I've added -depth 24 to the vncservers configuration and verified that it's running with that bitdepth in xdpyinfo, but unable to figure out where to set 32 bits per pixel.
