I'm experiencing the same issue using the 2.2.1 version of the Intel driver on a Dell Inspiron 500m. Everything works in normal orientation, but when I rotate left, Totem (and the Firefox plugin) hangs the system when it's trying to display either a video or a visualizer.
I tried to change the video output from v4l2 to v4l with gstreamer- properties, but it didn't make any difference. I'm currently running a multi-head setup, but the problem occurs also when using only the laptop's own TFT. Here's output from lspci and xdpyinfo: # lspci -vvvv 00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02) Subsystem: Dell Unknown device 0153 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0 Region 0: Memory at e8000000 (32-bit, prefetchable) [size=128M] Region 1: Memory at faf00000 (32-bit, non-prefetchable) [size=512K] Capabilities: [d0] Power Management version 1 Flags: PMEClk- DSI+ D1+ D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- $ xdpyinfo name of display: :0.0 version number: 11.0 vendor string: The X.Org Foundation vendor release number: 10400090 X.Org version: 1.4.0.90 maximum request size: 16777212 bytes motion buffer size: 256 bitmap unit, bit order, padding: 32, LSBFirst, 32 image byte order: LSBFirst number of supported pixmap formats: 7 supported pixmap formats: depth 1, bits_per_pixel 1, scanline_pad 32 depth 4, bits_per_pixel 8, scanline_pad 32 depth 8, bits_per_pixel 8, scanline_pad 32 depth 15, bits_per_pixel 16, scanline_pad 32 depth 16, bits_per_pixel 16, scanline_pad 32 depth 24, bits_per_pixel 32, scanline_pad 32 depth 32, bits_per_pixel 32, scanline_pad 32 keycode range: minimum 8, maximum 255 focus: window 0x3a00022, revert to Parent number of extensions: 33 BIG-REQUESTS Composite DAMAGE DOUBLE-BUFFER DPMS Extended-Visual-Information GLX MIT-SCREEN-SAVER MIT-SHM MIT-SUNDRY-NONSTANDARD RANDR RECORD RENDER SECURITY SGI-GLX SHAPE SYNC TOG-CUP X-Resource XAccessControlExtension XC-APPGROUP XC-MISC XFIXES XFree86-Bigfont XFree86-DGA XFree86-DRI XFree86-Misc XFree86-VidModeExtension XINERAMA XInputExtension XKEYBOARD XTEST XVideo default screen number: 0 number of screens: 1 screen #0: dimensions: 2024x1400 pixels (535x370 millimeters) resolution: 96x96 dots per inch depths (7): 24, 1, 4, 8, 15, 16, 32 root window id: 0x5a depth of root window: 24 planes number of colormaps: minimum 1, maximum 1 default colormap: 0x20 default number of colormap cells: 256 preallocated pixels: black 0, white 16777215 options: backing-store NO, save-unders NO largest cursor: 64x64 current input event mask: 0xfa8033 KeyPressMask KeyReleaseMask EnterWindowMask LeaveWindowMask ExposureMask StructureNotifyMask SubstructureNotifyMask SubstructureRedirectMask FocusChangeMask PropertyChangeMask ColormapChangeMask number of visuals: 8 default visual id: 0x23 visual: visual id: 0x23 class: TrueColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits visual: visual id: 0x24 class: TrueColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits visual: visual id: 0x25 class: TrueColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits visual: visual id: 0x26 class: TrueColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits visual: visual id: 0x27 class: DirectColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits visual: visual id: 0x28 class: DirectColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits visual: visual id: 0x29 class: DirectColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits visual: visual id: 0x2a class: DirectColor depth: 24 planes available colormap entries: 256 per subfield red, green, blue masks: 0xff0000, 0xff00, 0xff significant bits in color specification: 8 bits -- web page -> X server crash/blank, no display until reboot [Q965] https://bugs.launchpad.net/bugs/225400 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
