Bug 101790

Created attachment 132688 [details]
Linux messages

By the way, there is nothing in the Linux messages, even with `drm.debug=0xe`, and in the X server log files.

If you cat /sys/kernel/debug/dri/0/i915_display_info that should show the actual location of the hw cursor as well. Can you attach Xorg.0.log or equivalent?

Please test

Thank you. That fixed it.

Tested-by: Paul Menzel <paulepanter@users.sourceforge.net>

Just a note regarding the test `kms_cursor_crc` in the Intel GPU tools.

There is still another issue, where pasting text with the middle mouse button doesn’t appear right away. I created bug #101819 for this.

I also encountered this issue (mouse pointer not moving) testing an old netbook with a 945GME with the drm-intel-nightly branch cloned the evening of July 7th. I applied the original patch supplied and it fixed the problem for me.

Thank you for the feedback. Daniel applied this patch already, so the final 4.13 release won’t have it.

David, do you also experience the paste issue, cf bug #101819?

Elizabeth please note, that the commit description [1] mentions, that it also does not work on PNV.
