damaged windows fail to redraw

[Jeffrey Baker]

Binary package hint: xserver-xorg-video-intel

On Intrepid Alpha 5 + latest updates, I get visual glitches when damaged windows fail to redraw. I did not have this problem in Hardy. The attached screenshot shows an example of the problem.

xserver-xorg 1:7.4~2ubuntu1

By the way, I use metacity, not compiz.

Thank you for the bug report.

Coul you try the latest 2.5.0 release of the driver to see if the problem goes away:

Thanks,

Sure, I'll be happy to, but being slightly averse to building it right now I'd be grateful if you could point me to a distro or livecd that already packs the 2.5 driver.

I'm not aware of one, but that doesn't mean that one exists, (I haven't followed any recent distribution snapshots or live CDs, etc.).

I can understand your hesitance to entirely break a working system, but it can actually be fairly simple to compile this driver and use it without installing anything. Here's the basic recipe I use:

1. Download and untar the driver

2. Change into the new source directory and:

    ./configure && make

3. Make a local copy of your X configuration file:

    cp /etc/X11/xorg.conf .

4. Edit that file and add a section like the following at the top:

      Section "Files"
        ModulePath "/home/username/src/xf86-video-intel/src/.libs"
        ModulePath "/usr/lib/xorg/modules"
      EndSection

   Edit the /home/username/src/ portion to match the actual directory where you untarred the driver source. This will direct the X server to look in the directory where the driver is compiled, (but never installed).

5. Finally, start an X server, pointing it at your custom config file. Something like:

   X -config /home/username/src/xf6-video-/intel/xorg.conf :0 & sleep 1 && DISPLAY=:0 xterm

   This starts an X server, waits one second, then starts an xterm. You can modify the command to start whatever else you like. Or from within that xterm you can then run something like "gnome-session" or "startkde" or similar to get a complete session.

Do let me know if you have any trouble with that---otherwise I'll look forward to whatever report you can provide.

Xorg.0.log with driver 2.5.0

You left out the part about building a private libdrm and setting DRM_LIBS and DRM_CFLAGS :-)

Anyway, I was able to reproduce the problem still with 2.5.0. Scrambled contents of damaged windows is still the symptom.

I would note that I can't make this happen with Compiz, only with Metacity. Perhaps there is a non-compositing, non-render drawing path that's being overlooked if the developers and testers are mainly using Compiz?

This bug was reported in the Intrepid development cycle; removing regression-potential and marking as regression-release.

[Bryce Harrington (bryce)]

[This is an automatic notice.]

We'd like to forward your bug upstream, however upstream requires
that you first test it against their newer driver code.

To save you the effort of building the driver from source, we've built
packages for the driver and its new dependencies.

So you have a couple options:

 1. Download and test .debs for intrepid, from:
     https://edge.launchpad.net/~intel-gfx-testing/+archive

 -or-

 2. Download and test the Jaunty alpha-2 (or newer) Live CD,
     (which includes a beta of the new xserver 1.6 as well).
     See http://cdimage.ubuntu.com/releases/9.04/ for ISOs

Thanks ahead of time! You can simply reply to this email to report your
findings.

P.S., if you wish to forward your bug upstream yourself, please follow
these directions to do so:

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

With the latest released bits I can no longer reproduce this.
