Though I'm not sure about which driver for the Radeon card is the culprit? I'm using ATI's drivers. I am doing one other thing though that MIGHT be what makes it work. I added this line to the section "Device" in XF86Config: VideoRam 32768 I don't do games so it's not a problem for me (not that 32mb is that little) I added this because I had issues with memory locking failed (under kernel 2.4). It seems that QT indeed maps video memory into it's memory space, and not only that, it appears to add it several times. I have a Radeon 9200 with 128mb memory, which should mean that memory would increase with 128mb but I remember launching MusE ,which normally takes about 50mb of memory in debug build, taking over 300mb of memory! My (non verified) conclusion was that it has added the video memory several times. I did however not experience any problems as serious as what is being described and I don't recall ever having seen it, apps failed to launch though. Do try this trick and let me know if this makes any difference. If it does not, then I assume there are more pieces to this puzzle that still are not identified.
