I have a Mac Mini with Intel 945GM chipset, including Intel 950GMA.
After desktop problems on recent builds of Ubuntu I am running sidux with kernel 2.6.26-0.slh.6-sidux-686, upgraded using smxi.
I have installed and set up virtualbox.
The desktop problems I found on ubuntu are much the same on sidux.
My sidux desktop display flashes intermittently and seems unstable.
Once had complete lockup (black screen and no input handling) after running virtualbox and then viewing flickr photos. On ubuntu this type of lockup occurred at least once an hour but there I only had it when running virtualbox.
I found that lockup and screen flashing will stop (or get much less) if you edit xorg.conf and add in the line
Option "DRI" "false"
in the Device section, then restart X.
(This issue is discussed at launchpad.net under #226272)
However, this is not usable because X then fails to render properly.
The symptom is an apparent freeze of the desktop (maybe the mouse will still move). If you switch to another VT (VT1) and then back to VT7 the desktop is live again and things you tried to do before have happened. Typing will be completed, a window will have opened or moved the way you expected it to. This means input is still being handled but the X rendering has become invisible.
The desktop stays live only for a minute or two before freezing again.
This (DRI?) problem makes X unusable on my hardware with recent builds of linux. It has only appeared in the last month. Earlier builds are OK. |

No replies so I presume this is is not a problem for anyone else.
Anyway I've deleted sidux and installed Ubuntu 8.04.01 now. Ubuntu is more stable but still has screen flashes and I once had a complete lockup. The screen flashes in Ubuntu can be removed completely by disabling DRI in X, but this is the action that previously made sidux unusable.
I have not had such problems using Linux before, so something happened in the distributions about two months ago that pushed X into instability - at least with my Intel 945 chipset. |
