This is identical to bug 1804885, but as requested I am filing this while
running the standard Ubuntu kernel. I will copy and paste my summary below.

* This occurs with the mainline PPA 4.18.12-041812-generic kernel.
* The glxinfo sectio
Public bug reported:
When I start a VirtualBox virtual machine (reproducible with the Ubuntu
18.04/VirtualBox 5.2.22 packages from virtualbox.org) with VMSVGA
emulation and 3D pass-through enabled, my system hangs. Sometimes I can
recover if I get to a VT fast enough to kill the process. Also, t
I am currently running version 1.8.4-0ubuntu0.17.10.1 of both packages

have started seeing mouse button freezes after sus
I must admit that I have not seen this freeze for a while (unless I just
missed it among all the swap-to-death freezes I have had recently), but
I installed the packages. I did not enable proposed, I just manually

I have been having regular system freezes after switching from using my

Public bug reported:
When starting a VirtualBox virtual machine using VMSVGA emulation on
Ubuntu 17.04 I get a crash. I tracked this down to the Intel code in
libdrm and Chris Wilson committed the fix to git as 19c4cfc5. I
verified that the crash occurs with libdrm build from git before but not

I am now no longer seeing the flicker and resolution issues much (and
poking the hardware, e.g. by opening the Display control panel usually
gets rid of it). I have a suspicion there might be hardware issues too.
The mouse cursor issue is still present with kernel 4.2.0-7-generic, and

I was previously reporting this on bug 966744, which is however now
marked as fixed and we are requested to open new reports. This is an

Public bug reported:
I need to build certain X11 software for an i386 target on my amd64 box.
The following packages do not support multi-arch installation:
libice-dev libsm-dev libxext-dev libxmu-dev libxrandr-dev libxrender-dev
libxt-dev
However, a quick check after installing the i386 version
I intercepted this in gdb, with the following result (unfortunately I
couldn't find a debug symbol package for the evdev driver):
Program received signal SIGSEGV, Segmentation fault.
0x00960600 in ?? () from /usr/lib/xorg/modules/input/evdev_drv.so
(gdb) bt
#0 0x00960600 in ?? () from /usr/lib/xo
My first instinct would be to try the following patch. Looking at the
server source code I don't think that read_input will be called in a
loop if it returns without doing anything, and I would assume that the
server will get notification from udev on a separate path to trigger
device removal even
pInfo->read_input -> EvdevReadInput -> EvdevMBEmuFinalize ->
RemoveBlockAndWakeupHandlers -> handlers[i].deleted = TRUE;
Do I recall correctly that read_input is called from the SIGIO handler
in the X server?

I note that in
(gdb) p handlers[i]
$2 = {BlockHandler = 0x9604b0, WakeupHandler = 0x9605e0,
blockData = 0x8fd06f8, deleted = 1}
the value of deleted is 1. WakeupHandler() actually checks that - some
concurrency issue?

Just tested again. I no longer see this on bare metal (I think I did
before, but it was so long ago...) I do see it in VirtualBox (Oneiric
VM) with and without Guest Additions installed. I will take fifteen
minutes to see if I can debug it.
