On a closer look, pressing the brightness up or down key makes a
difference: With the up key brightness is set to its highest level, with
the down key its set to the highest level - 1.
Btw. the newest driver 2:2.99.916+git20141006.ec2b9ac8-0ubuntu0sarvatt
shows the same behavior.

Public bug reported:
After logout, switching to another login screen or shutting down the
monitor brightness is set to its lowest level, making it rather hard to
read in bright environments. Pressing a brightness key once (up or down
does not matter) sets the monitor brightness to its highest
This is now fixed upstream:

Ok, thats weird: I still get the striped borders occasionally on a fully
updated trusty, but only when I use the Greybird-compact xfwm4 theme (or so it
seems). I replaced therefore all the left-*, right-*, bottom-* xpms of the
theme with those of the normal Greybird theme and didn't see striped
This should have been fixed by the upgrade to 2.99.909, now 2.99.910.
Unfortunately not for me (c.f. attached screenshot). I still can
reproduce the border issue (with and without the compositor) quite
frequently.

Oh, wait. Did this mean by upgrading *from* 2.99.909 to 2.99.910? If
so, please ignore my previous comment, since I'm clearly running
2.99.909.

I should mention, that in contrast to the original report, the stippled window
borders appear now independent of the compositor state (on or off).
I've also tested xfwm4 in combination with compton (standalone opengl
compositor) with the same result: occasional appearance of stippled borders.
I've updated the packages from the mentioned ppa. Additional to the
border issue I get now quit frequently character distortions (cf. the
second (II)- line in the screenshot of the terminal window) in
different programs.
Please note (cf. comment #31), that using a compositor or not does not
seem
Another annotation: I have the striped borders issue also on my desktop
system: xubuntu 13.10, Intel i5-4570S with integrated hd4600 gpu. So I
guess this issue isn't limited to a single set of hardware.

I've played around a bit with the trusty daily image. So far I couldn't
trigger any heavy distortions. The stippled window borders (c.f.
attached screenshot) however still do occur occasionally (but with
reduced frequency than before).

Same in single user mode, so I guess its a kernel issue.

Just to summarize the kernel log on failures (and making this issue
easier to locate):
[ 730.725409] [drm:intel_ddi_pll_mode_set] *ERROR* No WRPLLs available!
[ 730.725413] [ cut here ]
[ 730.725429] WARNING: CPU: 1 PID: 2213 at
Attached full dmesg with drm.debug=0xe boot option.
Additionally I unplugged/plugged the dvi/vga port after the second
resume. The log shows, that those events get registered, but still no
video output (monitor goes into power save).
** Attachment added: dmesg_drm.debug_hotplug
I can now reproduce it by hibernating two times. As the attached dmesg shows,
resume after first std works fine, resume from the second std onwards results
in no video output.
As it may be a kernel issue, I tested it with the 3.11 saucy and the 3.12 tusty
kernel. Both show the same behavior.
Public bug reported:
I'm trying to enable a reliable hibernate/resume cycle on a intel haswell
cpu/gpu system with ubuntu 13.10 +xfce. Until now I've failed, because I get
three possible outcomes, when resuming (without seeing any pattern). In all
cases pm reports, that 'Image restored
I get glitches too on a freshly installed Xubuntu 13.04beta1 (view attachment).
However in my case it's somehow correlated with the compositor (xfwm4), which
must be switched on to get the artifacts. I don't have gpu hangups.
