I have also suffered this twice or thrice over the last weeks. I am banging myself on the head for not having noticed this early, but this was probably caused because I've been testing gutsy with oh so many drivers (8.34, 8.36, 8.40, ati 6.7.19*...). In any case, I'm the owner of a Mobility Radeon 9600, and I'm currently running the fglrx available on the official repositories.
I am also attaching the two dmesgs I had, dmesg.0 being the one that crashed right when going to gdm and dmesg being the normal boot one. Please note that in one of these I inserted the receiver of my Logitech V450 laser wireless mouse. However, I've done this before during boot, without negative consequences. Difficult reproducibility hurts. lspci -vvnn 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] [1002:4e50] (prog-if 00 [VGA]) Subsystem: Dell Unknown device [1028:2001] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop+ ParErr- Stepping- SERR+ FastB2B- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 255 (2000ns min), Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 11 Region 0: Memory at d0000000 (32-bit, prefetchable) [size=256M] Region 1: I/O ports at c000 [size=256] Region 2: Memory at fcff0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at fc000000 [disabled] [size=128K] Capabilities: [58] AGP version 2.0 Status: RQ=80 Iso- ArqSz=0 Cal=0 SBA+ ITACoh- GART64- HTrans- 64bit- FW+ AGP3- Rate=x1,x2,x4 Command: RQ=32 ArqSz=0 Cal=0 SBA+ AGP+ GART64- 64bit- FW+ Rate=x4 Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- ** Attachment added: "The dmesg that resulted from the crash" http://launchpadlibrarian.net/10467145/dmesg.0 -- [Gutsy]Random Black Screen while loading GDM https://bugs.launchpad.net/bugs/154820 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
