Bug Description

Binary package hint: x11-xserver-utils

I'm using Latest Jaunty as at Apr 3, 2009, 3PM. Running xrandr --scale XxY or xrandr --transform ... ends in a segfault in xrandr. The transformation is not applied.

I'm running Xorg with an empty xorg.conf on a Radeon HD 3600 using the radeon driver (/usr/lib/xorg/modules/drivers//radeon_drv.so). I've seen the same problem with a Radeon X1200 (AMD 690G) using the same driver.

that's because the driver only supports randr 1.2, and scale needs 1.3. Try 9.10 alpha3 livecd.

xrandr --output <bla> --scale or --transform works fine with Jaunty. The segfault only happens when I omit the --output parameter. In a way it makes sense, since --scale and --transform are output-specific. Would be nice though, if xrandr could print an error message pointing out my mistake instead of just crashing.

Please check if it is still happening with Karmic, before we send it upstream. Thanks ahead of time.

Still happens on Karmic with x11-xserver-utils 7.4+2. I ran xrandr --scale 1x1 which resulted in a segfault.

[This is an automatic notification.]

A new version of the -ati driver is now available in Karmic.

This is a significant update to -ati which brings in kernel mode-setting
(currently disabled) and scores of fixes for DRI2, EXA, etc.

I've posted the new version of this driver to the following PPA,
would you mind testing it and seeing if it resolves the bug you
reported?

https://edge.launchpad.net/~bryceharrington/+archive/ppa/+sourcepub/709908/+listing-archive-extra

If you're not running this release of Ubuntu, you can try booting the Karmic
LiveCD and loading the PPA onto it, and then log out/in to restart X.
ISOs are available at http://cdimages.ubuntu.com/releases/

After testing Karmic, report back here whether it's still an issue or not,
and if it is please post a fresh Xorg.0.log and 'dmesg' output.

Note there could be new bugs... please file these as new reports using
the command 'ubuntu-bug xorg'.

The problem persists with the new Radeon driver PPA. I strongly suspect that this problem is not driver-specific.

xrandr --output VGA-0 --scale 0.5x0.5 works as expected
xrandr --scale 0.5x0.5 segfaults.

It should report an error message instead of just crashing.

Running xrandr --scale 1x1 or --transform, without specifying --output, causes crash.
