[Bug 146859] Re: No dri (and therefore no compiz) for virtual screen greater than 2048x2048
Windows XP and OS X work around this hardware limitation, most likely by doing the same thing as the shatter work for Xorg. Basically it splits the screen into shards and renders them separately which works around the limitation. However, there is a still a lot of work that needs to be done for this to work in Xorg so I would not expect to see it any time soon. Maybe in a year or so at the rate it has been going so far. -- No dri (and therefore no compiz) for virtual screen greater than 2048x2048 https://bugs.launchpad.net/bugs/146859 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

Regarding Martin's post #62: Forgive me if this is a dumb question, as I'm new around here -- you say there's a _hardware_ limitation with the i915/i945 cards and DRI at 2048. Why is it that WinXP can run DX9 quite satisfactorily on the same hardware? I'm running 2 monitors, 1900x1200 1600x1200, and playing around with dual-booting XP and Mint7. My XP extended desktop at 3520x1200 works beautifully. But when I boot up Mint7, using the latest kernel (2.6.31-rc6) and updated xorg-edgers drivers, I kiss acceleration goodbye above 2048. I'm trying really hard to make Mint my default environment at work, but I have to keep going back to XP because my second monitor, sitting blankly, is silently mocking me.

[Bug 146859] Re: No dri (and therefore no compiz) for virtual screen greater than 2048x2048
The comments in this bug are raising a range of different issues for different cards (DRI, UXA/EXA accel vs noaccel, different chipsets are what not). Lumping together a lot of issues mostly makes the bug reports messy and unusable. There is no point in posting further comments to _this_ particular bug. Now, if anyone had better experience in a previous version of Ubuntu (better performance, better handling of dual screen etc), then we're dealing with a new regression for that hardware. In so, please use the command ubuntu-bug xserver-xorg-video-intel to file a _new_ bug report that deals with your issue on your chipset specifically. As for the question about the hw/sw driver limitation.. Basically for gen3 hardware and earlier (that's 915/945 and older) there is a _hardware_ limitation, however, if you go to great lengths it's technically possible to circumvent that limitation using a software workaround. Doing so would likely incur a significant runtime performance penalty and it would also be a significant amount of work for very little gain compared to other potential efforts... that said, just as you point out, it can be done. The upstream developers have at this time, however, opted to prioritize things like UXA, KMS, DRI2 etc and have basically said they are unlikely to hack around the hw limitation. If someone is prepared to step up and create a driver capable of 2048 sized DRI for these 915/945 and older cards, we'd be happy to ship it of course but if there isn't anyone interested in implementing it there is no point in having a bug tracking it.

I registered for this bug because of this problem on a X4500, which certainly does support larger textures but is artificially limited to 2048×2048.

My symptoms seem to have similar causes, but I'm not sure if this is the same bug. I upgraded to the Jaunty RC on April 17, and had decent luck running DRI and UXA on a dual-screen Virtual 2944x1200. X did crash every couple of hours, but while it ran, the performance was great, glxgears 1100+fps, smooth alt+tab switching, great cube switching. On April 18, I upgraded to the mesa 7.4-0ubuntu3 packages (glx, libglu, dri, etc..), and compiz would not start. It complained about the MAX_TEXTURE_SIZE of 2048 and fell back to metacity. When I downgraded to the mesa 7.4-0ubuntu2 packages, compiz worked fine. I did this upgrade/downgrade a few times to make sure. So I just did bamed's TEXTURE_LIMIT=4096 hack above, but glxinfo -l also reports a GL_MAX_CUBE_MAP_TEXTURE_SIZE_ARB = 2048 which is what I assume is limiting how my right-hand screen handles redraws and the desktop cube. -- No dri (and therefore no compiz) for virtual screen greater than 2048x2048 https://bugs.launchpad.net/bugs/146859 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

[Bug 146859] Re: No dri (and therefore no compiz) for virtual screen greater than 2048x2048
I know it's a hardware limitation to 2048x2048 when using DRI, but what about when not using DRI? As I said, when I set a virtual desktop size greater than 2048x2048, the driver is switched to software renderer, as shown above.

Definitely fixed; I've used compiz on extended desktops larger than 2048x2048 in Jaunty with the standard packages. -- No dri (and therefore no compiz) for virtual screen greater than 2048x2048 https://bugs.launchpad.net/bugs/146859 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

Is that fixed with todays upload of mesa 7.4 to the jaunty repos?

[Bug 146859] Re: No dri (and therefore no compiz) for virtual screen greater than 2048x2048
As far as I know, Intel graphics older than the 965 do not support textures above 2048x2048. The Intel driver supports textures larger than that on appropriate hardware already, and has done so for quite a while. Support in Mesa was the missing part, and has now been fixed upstream. -- No dri (and therefore no compiz) for virtual screen greater than 2048x2048 https://bugs.launchpad.net/bugs/146859 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
[Bug 146859] Re: No dri (and therefore no compiz) for virtual screen greater than 2048x2048
The value reported by glxinfo is not accurate. Probably a bug in the driver. One ugly workaround that works is to edit /usr/bin/compiz and hard set the value of TEXTURE_LIMIT. So find the line: TEXTURE_LIMIT=$(glxinfo -l | grep GL_MAX_TEXTURE_SIZE | sed 's/.*=[^0-9]//g') and change it to something like: ##Commented out to fix bug in driver ##TEXTURE_LIMIT=$(glxinfo -l | grep GL_MAX_TEXTURE_SIZE | sed 's/.*=[^0-9]//g') TEXTURE_LIMIT = 3000 Not pretty, but it works! -- No dri (and therefore no compiz) for virtual screen greater than 2048x2048 https://bugs.launchpad.net/bugs/146859 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

** Summary changed: - No dri for virtual screen greater than 2048x2048 + No dri (and therefore no compiz) for virtual screen greater than 2048x2048 ** Description changed: Scenario: Toshiba L20 laptop, with builtin 1024x768 builtin LCD, Intel i915 graphics card. External monitor of 1280x1024 resolution Using the default configuration (after dpkg-reconfigure -phigh xserver- xorg): mte...@sombra:~$ xrandr -q Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024 VGA disconnected (normal left inverted right) LVDS connected 1024x768+0+0 (normal left inverted right) 304mm x 228mm 1024x768 60.0*+ 800x60060.3 640x48059.9 TV disconnected (normal left inverted right) With this default configuration, the maximum width (1024) is not enough for a multimonitor mode using my two monitors (1024 + 1280), so, I changed my Display Screen subsection to: SubSection Display Modes 1024x768 Virtual 2304 1024 EndSubSection After this, I'm able to setup a multimonitor mode using randr, but DRI is no longer available. I'm getting this log: (EE) intel(0): Cannot support DRI with frame buffer width 2048. So, no compiz, no google-earth, no fancy screensavers,... I've found this thread where it seems that the coordinate registers for the 3D engine are only 11 bits: http://lists.freedesktop.org/archives/xorg/2007-June/025501.html BTW, I tested a hacked OSX version on this box some time ago, and it was able to operate Quartz Extreme with both screens at the same time without problems. Probably the screen/display design could be the problem? I find it frustrating, as with a relatively new graphics card I'm not able to use two monitors (with a not that high resolution) and hardware accelerated display at the same time. + + [Workaround] + For now, you must not use a Virtual setting larger than 2048x2048 (or 1024x1024 on some chips, or 4096x4096 on some others) if you wish to use compiz.
