Bug ID: 99533
Summary: black screen after switching session
Product: Mesa
Version: 17.0
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/i965
Assignee: intel-3d-bugs at lists.freedesktop.org
Reporter: Martin at Lichtvoll.de
QA Contact: intel-3d-bugs at lists.freedesktop.org
I was testing Linux kernel 4.10-rc5 to see whether the hang/lock up issues with
4.9 have been gone. Meanwhile I also received mesa 17.0.0~rc1 via Debian
Sid/Unstable packages. I am using the Modesetting driver with glamor. Hardware
is ThinkPad T520 with Sandybridge graphics – I am back at kernel 4.8 again as I
need this laptop for work, I am not willing to do a bisect for an occasionally
happening issue that can lead to data loss due to having to forcefully switch
of the machine:

Hardware:
Processor: Intel Core i5-2520M @ 3.20GHz (4 Cores), Motherboard: LENOVO
42433WG, Chipset: Intel 2nd Generation Core Family DRAM, Memory: 16384MB, Disk:
300GB INTEL SSDSA2CW30 + 480GB Crucial_CT480M50, Graphics: Intel 2nd Generation
Core Family IGP, Audio: Conexant CX20590, Monitor: P24T-7 LED, Network: Intel
82579LM Gigabit Connection + Intel Centrino Advanced-N 6205
Software:
OS: Debian 9.0, Kernel: 4.8.15-tp520-btrfstrim+ (x86_64), Desktop: KDE
Frameworks 5, Display Server: X Server 1.19.1, Display Driver: modesetting
1.19.1, OpenGL: 3.3 Mesa 17.0.0-rc1, File-System: btrfs, Screen Resolution:
3840x1080
With 4.10-rc5, but not with 4.8.x I occasionally have a black screen after
switching between two desktop sessions. Both are Plasma sessions, one is on
TTY7, the other on TTY8.
# How to reproduce
Honestly I do not know yet. It only happens occasionally. What I did:
1. Have two Plasma sessions open.
2. Work on TTY8.
3. Switch to TTY7 by pressing Ctrl-Alt-F7 after a while.
It doesn´t happen all the time.
# Actual results
Black screen and backtrace in kernel log:

Jan 25 12:05:58 merkaba sddm[1898]: Removing display ":1" ...
I wonder about the sddm messages. Maybe the traces just appeared as I typed
"reboot" via SSH from another laptop, but not before.
The black screen might be due to the GPU hang in combination with Plasma screen
lock handling. When I press Ctrl-Alt-L kwin locks the screen, but there is a
certain delay sometimes. When I switch to user session before the lock screen
appears, display on original TTY seems to be frozen (maybe due to
systemd-logind session handling). When I then switch back I have a black screen
for a short moment, but then it displays the lockscreen.
# Expected results
Either lockscreen or content of other session displayed.
