Description Edward Z. Yang 2011-12-01 12:17:09 UTC
I'm using the 'redshift' application, which uses 'xcb_randr_set_crtc_gamma_checked' in order to adjust the gamma on my screen.

Unfortunately, when I perform a screen rotation using xrandr, these settings get reset back to default!

I believe this was a regression between the version of X.org shipped with Natty and Oneiric.

While you believe it's a regression, can you confirm that it is a regression in the *server* not some driver issues?

Also, what versions (video drivers and server) were you using when it worked and when it failed?

Xorg log for version (with bug)

Here is my Xorg.0.log, from what I believe is the version which has the bug.

Log from Xorg, probably without bug, but not sure

Here's an old Xorg log I found lying around on my system. I'm not sure if it corresponds, but looking at the kernel version there is a high probability it does.

Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server.
