Public bug reported: Binary package hint: xserver-xorg-video-i810
System: Dell Inspiron 510m, 256mb RAM, Intel 82855GM graphics chipset, Edgy final & all updates I am having multiple issues with my graphics card since (clean) upgrading from Dapper to Edgy. Although these could be split into separate bugs, it's unclear as to whether they are the combined symptoms of one bug or not, so I'm keeping them together for now. Here are the issues with my system since upgrading to Edgy: 1. When logging in or restarting X, garbage is displayed on-screen for a second before the server starts, sometimes showing evidence of previous graphical activity (e.g. a distorted image from a movie that was previously playing). Additionally, restarting X too many times will result in a non-starting X server (I'll reproduce that in logs if requested). 2. In Edgy, 3D performance has worsened. I know glxgears is not a benchmark, but on the same system in [EMAIL PROTECTED], Dapper achieves ~900fps, whilst Edgy gets ~530fps by default (16bit has a similar performance gap). If I disable powernowd in Edgy, I can improve the score to ~670fps, but Dapper exhibits equal fps rates when powernowd (CPU scaling, supported by my processor) is enabled or disabled. Performance is noticeably sluggish in games, running compiz/beryl, etc. Enabling or disabling Composite/AIGLX seems to make no significant difference, and I will do more thorough benchmarks & logging if necessary. Note that 2D performance is unchanged. 3. Specifying Option "SWCursor" "true" in xorg.conf seems to totally break DRI. I'm not sure if this is normal behaviour. 4. While in [EMAIL PROTECTED] mode, switching to a VT, resuming from suspend, or even closing and reopening the lid will result in an invisible cursor when X re-initializes. The cursor is still functioning - buttons become highlighted as the cursor (presumably) passes over them, and it is possible to click, drag and so on. This problem does not seem to occur in [EMAIL PROTECTED] mode. 5. With Edgy's i810 driver, I received several warnings in my Xorg.0.log: "(WW) I810(0): xf86AllocateGARTMemory: allocation of 8 pages failed" This line repeated several times, with the page count increasing each time. I'll produce a log of this if required, but it is identical to this user's log: http://www.ubuntuforums.org/showpost.php?p=1682450&postcount=1 Regarding bug #4&5: I have compiled&installed the latest drm and xf86 -video-intel from git (using checkinstall for a relatively clean upgrade). This has solved bug #4&5 (the cursor restores correctly, and Xorg.0.log no longer warns about allocation failures), but not the others. I have also attempted to compile&install Mesa from cvs, but performance was unchanged. (I compiled xf86-video-intel from the master branch; modesetting did not properly illuminate the LCD screen when X started) Any assistance would be much appreciated. Below is my /proc/mtrr output, I will shortly post my xorg.conf, Xorg.0.log and dmesg output from my system running Edgy with the latest drm & xf86-video-i810 from git installed (not exhibiting bug #4&5). Let me know what other logs would be useful. /proc/mtrr: reg00: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1 reg01: base=0x0ff00000 ( 255MB), size= 1MB: uncachable, count=1 reg02: base=0xfeda0000 (4077MB), size= 128KB: write-through, count=1 reg03: base=0xf0000000 (3840MB), size= 128MB: write-combining, count=1 ** Affects: xserver-xorg-video-i810 (Ubuntu) Importance: Undecided Status: Unconfirmed -- Multiple new issues with 855GM, Dapper -> Edgy https://launchpad.net/bugs/74751 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
