Bug 21223

It should be fixed in current master, can you confirm?

Current mesa master of course :)

Is there any easy way of testing this without screwing up my default Ubuntu Jaunty installation :) ?

I'm asking because the affected hardware is actually my work/coding laptop, so I cannot afford to mess too much with it timewise. Is it only necessary to install a newer set of radeon.ko/drm.ko or do I need to update libs as well ? 

No need to install anything, just set LIBGL_DRIVERS_PATH to the directory containing the self-built r300_dri.so. You can also set LIBGL_DEBUG=verbose to verify the right one is getting picked up.

Very nice approach indeed, I'll get this tested.

Didn't really work too well with the r300_dri.so driver from Mesa master:

oyvind@blackelf:~/tmp/build/mesa$ cd src/mesa/drivers/dri/r300/
oyvind@blackelf:~/tmp/build/mesa/src/mesa/drivers/dri/r300$ export DISPLAY=:0

I don't know how well the code from Mesa master in r300_dri.so is supposed to interact with the Mesa-installation in Ubuntu Jaunty ? Also, I got a build error when building the entire Mesa tree, but still managed to build the r300 DRI driver by itself.

Øyvind, you can also try the mesa packages from the xorg-edgers PPA https://launchpad.net/~xorg-edgers/+archive/ppa - the packages for Karmic are from current master head, and they will install fine in Jaunty. In addition you can install the Karmic kernel, which is based on 2.6.30-rc4.

Ok, I did the Ubuntu LiveCD+xorg-edgers-live-test script procedure, the upgrade worked fine. However, the screensaver crashes exactly the same as with a standard Ubuntu installation. I don't know if the upgrade included the supposed fix. I am unfortunately thus not able to confirm at this moment, but will look more into this later. I'll see if I can fix the Mesa build error and try again with the r300_dri.so driver, it did indeed give a different error. My main problem is, again, that the affected hardware is not a testing/play-machine, but my work-laptop which I need to keep in something of a working condition.

I booted an Ubuntu LiveCD, added the Karmic repo at https://launchpad.net/~xorg-edgers/+archive/ppa and did an apt-get dist upgrade. This updated at least Mesa with versions from xorg-edgers. Did an X restart and tested the lattice screensaver, but it still immediately freezes. 

Tested with the following Mesa-versions:
libgl1-mesa     7.6.0~git20090502.986d4a9e-0ubuntu...
libgl1-mesa-dri 7.6.0~git20090502.986d4a9e-0ubuntu...
libgl1-mesa-glx 7.6.0~git20090502.986d4a9e-0ubuntu...
libglu1-mesa    7.6.0~git20090502.986d4a9e-0ubuntu...

The above isn't related to that, if anything it's the X driver which isn't setting up enough GART memory (hence the suggestion to increase it with Option "GARTSize"). Can you attach the X log file?

Did you already see the above output when you reported this bug? Are you still seeing the r500SetupRSUnit output with the current driver?

A bit more data:

* This also happens on a Radeon Mobility X700 card 
  (system is Ubuntu Jaunty; all updates applied)


* Different behaviour occurs with the various --preset options:

lattice --preset 1   
  => kills the X server, can recover with Alt-SysRQ-K

lattice --preset 2
  => seems to work OK

lattice --preset 3
  => kills system stone dead (need a power-cycle to recover)
     #surely an X-server bug shouldn't kill the kernel?

lattice --preset 4
  => works for a few seconds, then stone dead.


Of the other screensavers in the rss_glx set, most of them work just fine:
hyperspace, helios, euphoria, skyrocket, solarwinds, plasma, fieldlines, flocks. Two of them seem to do abolutely nothing , but just stay black: cyclone and flux.


The RSS set seem to be pretty good at exposing fatal bugs in ATI drivers - I recall my Rage128 mobility being locked solid by one particular invocation of Euphoria about 5 years ago. I would suggest that they might make quite a good
reliability test for new drivers.

Confirmed on another X700 Mobility, with latest radeon-rewrite mesa and kernel 2.6.30-rc4.

This bug may be related to https://bugs.freedesktop.org/show_bug.cgi?id=21849

Maybe related, but the "bad" commit 4247ca942a16745da3d09c58996b276d02655a72 in 21849 never made it into the 2.6.28 kernel. I think the lattice issues here are even older. Looking forward to try the new kernel though.

It would be nice to get a response to comment #11...

I am having that issue with the Ubuntu 2.6.28 kernel which includes a backported radeon module.

A way to confirm it would be to try kernel 2.6.29.4 from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D that is the latest kernel without the bad commit.

Is this bug still reproducible with Ubuntu 9.10 (including mesa 7.6 and linux 2.6.31)?

Original reported of Ubuntu bug confirms this is no longer reproducible. Closing.
