radeon: [drm:drm_mode_getfb] *ERROR* invalid framebuffer id

Confirm, there is the same problem with the graphics card ATI radeon 5450.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug (or similar) also seems to affect RV516 based radeon cards.
Logs in with Unity 3D, but dock and tray icons not visible.
Unity 2D works fine.

I see this error in syslog when switching user from locked session. Screen goes black with cursor blinking upper left corner. With ctr-alt Fn I can still get the session. I't seems lightdm (and gdm) can not switch to locked session.
This is with open source radeon. With fglrx whole system freezes with black screen and only way out is hardware reset.

11.10 and Unity 3D, ATI HD 5700

I have a similar but different problem. When I lock my screen and come back, often times the screen will wake back up, but the dialog that normally appears to unlock the screen never appears. Sometimes I can go into virtual console and kill the screen saver daemon, and get back to my desktop, but it doesn't always work.

This is with the open source driver, and it's been a problem for quite a few releases for me. I'm trying the fireglx driver next, I seem to remember having other problems with that one in the past, but I'm desparate.

I'm experiencing similar problems with an Radeon HD 6700 graphics card: After resuming, I see the mouse pointer, but the unlock screen does not appear. In fact, it seems to be rather invisible but still active, as I am able to enter my password and unlock the screen blindly.

Switching to an text console, playing with xrandr and switching back results in screen corruption. Killing the X server with sysrq-k brings back an lightdm login screen (but obviously kills my session).

I am experiencing the same problem with Xubuntu 12.04, Xorg open source ati driver ,and an AGP X1950Pro 256M video card.

Right after login i land to a black screen, by pressing Ctrl-Alt-F1 i can log to a tty and see what is happening in the log.
When i enter
tail -f syslog
and then switch back to CTRL-Alt-F7, and the press Ctrl-Alt-Num+ (to switch to next available resolution), then the original error message appers in the tailed log:

[drm:drm_mode_getfb radeon] *ERROR* invalid frame buffer id

libdrm-radeon1 version is 2.4.40+git20130114.....
libdrm2 version is the same

my problem started about a week ago or so, which is suspiciouly near to that date in the version string

Status changed to 'Confirmed' because the bug affects multiple users.

As far as the framebuffer id error message goes, that is fixed for -intel.

Martin Wagner, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
