[Ubuntu-x-swat] [Bug 556782] Re: [rs690m] Graphics corruption with ati x1200
Hi all, I am a completely new Linux user. I moved from a totally broken Win XP environment to Ubuntu 11.04 a couple of weeks ago, expecting a streamlined, fast and functional system, with Unity 3D as a fancy GUI. But from the outset I have had diabolical issues with screen rendering corruption with the default Unity 3D setup and any apps in Unity 2D or even in Classic (no effects) which presumably use OpenGL which I wanted to use, e.g. Scilab (plotting), Oolite “Elite-like” game. The rendering corruption started right from the first: even the “try out” Ubuntu mode running from my USB drive during setup was afflicted! “Installing the whole Natty Ubuntu OS properly from disk will fix the problem,” I thought at first. I was wrong! Hardware: - Dell Dimension 5150 tower PC, 1GB physical RAM - Dual-core Intel Pentium 4 @ 3GHz - According to Ubuntu lspci -nn I have: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)] [1002:5b60] 01:00.1 Display controller [0380]: ATI Technologies Inc RV370 [Radeon X300SE] [1002:5b70] -Two monitors: 17” Dell LCD Model E176FPc driven by the 15-pin D-type video output; and an old Apple 19” monitor connected to the DVI output of this video card. Nothing connected to the S-Video socket. - Have used the monitors “control panel” in Ubuntu to configure an extended desktop across these two monitors, with the Dell as primary to the left, and the Apple to the right. Have uploaded some screenshots of the rendering issues in Unity3D (a complete wipeout, totally unusable) and within Unity2D and Classic (no effects). They remind me so much of a buffer overrun somewhere... I have no additional proprietary drivers installed, e.g. ATI/Radeon. I am loathe to install any because, having surfed widely to try and find a sure-fire resolution to this issue, I have seen so many cases where advised changes have messed up the user's system in their particular case that I have stopped short of making changes: I am too naïve a Linux user to start messing about with it to that level. Is this thread still running? In the spirit of offering up more evidence for the nature and scope of the rendering corruption issues out here in the community, would it be helpful if I described my symptoms in more detail...? I can describe various reproducible (on my system) instances if needed... ** Attachment added: "Unity 3D desktop, screengrab encompassing both screens" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/556782/+attachment/2423966/+files/U3D%2005%20Screenshot.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/556782 Title: [rs690m] Graphics corruption with ati x1200 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/556782/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Here's an example of how (presumably) OpenGL content gets stuffed even with correctly-rendered Ubuntu Classic (no effects) window surroundings... Just to confirm, this is ATI x300 (sorry if this is the wrong place for the report). ** Attachment added: "Selecting OpenGL screensaver within Ubuntu Classic (no fx)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/556782/+attachment/2423981/+files/GLSlideshow%2002%20U2D.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/556782 Title: [rs690m] Graphics corruption with ati x1200 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/556782/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

OK, eode and oliver-joos, I'll give your suggestions a shot.

[Ubuntu-x-swat] [Bug 556782] Re: [rs690m] Graphics corruption with ati x1200
UPDATE: The mods suggested above sadly did not help with Natty. I've done a total, clean install of 10.04 LTS UbuntuStudio (as I wanted the low-latency kernel for music apps). With UbuntuStudio 10.04: * Video so far works now without a hitch, straight out of the box with my ATI RV370 [Radeon X300] PCI card! * What I think is OpenGL content now works just as well as anything, and I haven't seen any rendering issues yet. Overall, video seems much more solid and stable. No further command-line mods or workarounds needed at this point in time. Not only that, but with the addition of just the Medibuntu package and alsa-firmware on top, I can even drive my EMU (Creative Labs) 0404 PCI soundcard for audio and MIDI as well! Next step: create the new bug report re: apocalyptic Natty rendering, as per Oliver's suggestion #89.
