** Description changed: Forwarding this (ancient) bug from a Ubuntu reporter: https://bugs.edge.launchpad.net/xserver-xorg-driver-ati/+bug/36596 [Problem] By default, the DefaultDepth is set to 24, however on this hardware this disables DRI. But when setting DefaultDepth to 16 it causes a system freeze. Possibly there is some relation with bug 16365, which has similar symptoms on the same hardware. [lspci] + 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon Mobility M6 LY [1002:4c59] + Subsystem: Compaq Computer Corporation Device [0e11:b11b] (II) PCI: 00:00:0: chip 8086,3575 card ffff,ffff rev 02 class 06,00,00 hdr 00 (II) PCI: 01:00:0: chip 1002,4c59 card 0e11,b11b rev 00 class 03,00,00 hdr 00 (--) PCI:*(1:0:0) ATI Technologies Inc Radeon Mobility M6 LY rev 0, Mem @ 0xd8000000/27, 0xd0100000/16, I/O @ 0x2000/8 [Original Report] This seems to be a general problem (it also occured when i used bug-buddy) but i can reproduce it easily using pan, among other methods. The steps to reproduce the problem are: a) run pan b) update a newsgroup c) quickly open task manager, stop the update task (using the stop icon) d) click on the "trash" icon e) system is frozen, e.g. mouse not moving, even ctrl-alt-f1 does not work. I also have a web server (apache2) running, and it is not accessible after the freeze. Another way to reproduce the problem is: a) run glxgears b) move the window around. Workarounds: a) After changing from ubuntulooks to clearlooks theme, it occurs much less frequently. b) After changing from xorg "ati" to "vesa" driver, it has not occurred yet (been using a few hours). (used together with "ubuntulooks" theme ) c) option "RenderAccel 0" works d) Disabling modules "dri" and "glx" works (at least as of June 2007) I first reported it against: - latest dapper as of 20060325, - pan 0.14.2.91. - kernel 2.6.15-19-686 #1 SMP PREEMPT Mon Mar 20 17:33:20 UTC 2006 i686 GNU/Linux . (I have also tried on kernel 2.6.15-19-386). Also reported as still occurring on: * Gutsy Alpha 4 (2007-08-21) - still freezes at DefaultDepth 16 * Hardy Alpha 6 (2008-03-10) - still freezes at DefaultDepth 16 * -ati 6.9.0 - still freezes at DefaultDepth 16 * [TODO: Test against 6.11.0] My problems with "ati" does not seem 3D related, I have tried disabling "dri" and "glx" modules and it still crashes. My system is a PIII Mobile 1GHz, 384 MB RAM, and Mobility Radeon M6 LY graphics. I am still able to get a system freeze at defaultDepth 16. At depth 16 DRI is on (at depth 24 there is not enough memory for DRI). Having said that, I myself do NOT have any requirements for defaultDepth 16 or DRI (just wanted to try some of the desktop effects). I would not object if defaultDepth 16 is not supported for an 8Megabyte M6. In trying older drivers, the problem seems to have started between 6.5.7.3 and 6.5.8. -- [Mobility M6 LY] System freeze with DefaultDepth 16 https://bugs.launchpad.net/bugs/36596 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
