Bisect what (i.e. why this is marked "bisect_pending")?

First comment already gives the bisected kernel commit.

You can get them either from the diff.gz file on the indicated package page:

Or doing "apt-get source xserver-xorg-video-intel" on the corresponding distro
and checking debian/patches/ dir.

Of the Ubuntu patches, I think the only one that might have some relevance is
revert-dpms-fix.patch, which is revert of commit
7d9a74622e5a936e4860fcef8358619bf59adae8.

Mouse cursor patch says following:
---------------
Prevent loss of mouse cursor after VT-switch
The mouse cursor becomes invisible after a VT-switch.
This is commonly seen on systems with light-locker that
switch to the login screen when locking.

This patch pulls from 4 upstream commits:
- 00a3adaf43640b9aaa84b8cb98c1f2f227686689
- 52c9d7ca2467bc273a8ef3c61c1b690ac56caa74

However, I don't think Intel DDX is that relevant for this because the issue
can be reproduced also with modesetting driver.


Chris, have you been able to reproduce the issue?
