Jussi Pakkanen, 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 linux <replace-with-bug-number>
** Changed in: linux (Ubuntu)

Intel graphics fails when bringing monitor out of sleep

Bug description:
I have a HP LP2475w monitor. Sometimes when the system has put it to
sleep, it fails in bringing it back up again. The screen remains
blank. Even changing virtual terminals with ctrl+alt+f1 does not work.
Ssh'ing in and running 'sudo service lightdm restart' makes it come
back up again.
This error shows up in dmesg:
[18380.721810] [drm:drm_edid_block_valid] *ERROR* EDID checksum is
invalid, remainder is 125
This monitor worked flawlessly on my previous computer which had
NVidia + the binary driver.
