On my Acer Emachine e625 laptop, enabling MSI seems to be an improvement. `vblank_mode=0 glxgears` give me 690 FPS when I had 590 without MSI.
However, the desktop experience (Unity 3D) feels the same with or without it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/755791 Title: [RS690M] No 3d acceleration in Radeon X1200 with new Gallium r300 / 3d drivers in 11.04 (Needs kernel quirk) Status in The Linux Kernel: Fix Committed Status in X.org XServer - ATI gfx chipset driver: Confirmed Status in “xserver-xorg-video-ati” package in Ubuntu: Triaged Status in Fedora: Unknown Bug description: The bug is active also in Freedesktop.org : https://bugs.freedesktop.org/show_bug.cgi?id=37679 [edit] The bug seems to be fixed with a patch provided by Freedesktop.org team. [/edit] [edit] This bug is caused by interrupts. They're not working. The solution for this problem is: - To see if Ubuntu 10.04 (where all things worked well) used UMS instead of KMS. - If Lucid used KMS, to bisect the kernel to see what change caused the problem. [/edit] [edit] The bug description, updated: The symptoms: No 3d acceleration (glxgears shows a black window, Unity doesn't start), *but* no fallback into the software-rendering mode (glxinfo reports that the 3d acceleration is working) The hardware: ATI Radeon RS690M X1200 series The version of Ubuntu: Ubuntu 11.04 (final release) [and Maverick also]. The behavior was also observed in Debian and Fedora 15, as noted below (so it seems not to be Ubuntu-specific). The version of xserver-xorg-video-ati: 1:6.14.0-0ubuntu4 (default in Natty). Same problems with the xorg-edgers PPA in Natty Beta2. The software affected: Compiz (doesn't start because requires direct rendering); then, Unity (just the wallpaper or black screen and the mouse pointer). glxgears, Stellarium, Blender, Adobe Flash Player in fullscreen mode and Visual module of Python work if software rendering is forced (but of course they run very very slow). The history of the bug: all worked as expected (out of the box) in 10.04, but in 10.10 the problems started. The workaround was to disable KMS, but now, in Maverick, since the new Gallium driver doesn't have a non-KMS mode, that workaround is not available. This issue was reported when using 11.04 Beta 1 and Beta 2, then, in the descriptions below there are some strange things (xorg crash during startup, software rendering fallback), that don't occur any more. The issue is just the description given here. The exceptions: **sometimes** (??) the 3d acceleration does work as expected, but at the moment there is no way for us to know when it will work or not [help please!]. And, sometimes the 3d acceleration work but is so slow that it seems to be actually software rendering. The workarounds: `vblank_mode=0 glxgears` (or other program) gives correct 3d accelerated output. `export vblank_mode=0` also allows to start Compiz and 3d acceleration works after running that. That is just a workaround and the problem is not solved yet. [/edit] Binary package hint: xorg I installed Ubuntu 11.04 Beta 1, and I'm not able to run Unity and Compiz, because I have no 3d acceleration. However, I was able to run Compiz once, the next time I booted, I don't know why, Compiz doesn't work. After several reboots, I see the following: 1. Sometimes (?), I have 3d acceleration via software rendering. When I run `glxinfo | grep render` I get: direct rendering: Yes OpenGL renderer string: Software Rasterizer GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_fragment_program, And if I run `compiz --replace`, I get the following error: Backend : gconf Integration : true Profile : default Adding plugins Initializing core options...done Initializing bailer options...done Initializing detection options...done Initializing composite options...done Compiz (opengl) - Fatal: GLX_EXT_texture_from_pixmap is missing Compiz (opengl) - Fatal: Software rendering detected Compiz (bailer) - Info: Ensuring a shell for your session prueba@prueba:~$ Window manager warning: Locale not understood by C library, internationalization will not work (metacity:2357): Gtk-WARNING **: Locale not supported by C library.

Sometimes, I have direct 3d acceleration, but it's unusable. glxgears doesn't work (black window). Also, if I run compiz, I get a blank screen (no Unity, no windows, just the mouse pointer and the background image). In this case, if I run `glxinfo | grep render`, I get: direct rendering: Yes OpenGL renderer string: Gallium 0.4 on ATI RS690 GL_NV_blend_square, GL_NV_conditional_render, GL_NV_light_max_exponent, So, I'm using the Gallium driver. I had a similar problem with Maverick and the radeon driver. I solved the problem turning off the Kernel Mode Setting (# echo options radeon modeset=0 > /etc/modprobe.d /radeon-kms.conf). I don't know how to do that with the Gallium driver. I want also to try using the radeon driver, but I don't know how to do it.
