[SOLVED] [debian testing mate] mouse cursor invisible from time to time

ardabro · 05-25-2016, 02:42 AM

Hi all
After last system update I experience two annoying behaviors and this thread is about the later:
From time to time mouse cursor is invisible after login. Sometimes when I switch to text console and back it helps, but sometimes not (even a couple of times).
What can be the reason? Any clues?

regards

your thread is lacking real information.
please read the first link in my signature.

still, i think it is a graphics related problem, so please post the output of the following commands:

Code:

uname -rvm
lspci -k | grep -iEA5 'vga|3d'

Thanks for reply.

Code:

> uname -rvm
4.3.0-1-amd64 #1 SMP Debian 4.3.3-5 (2016-01-04) x86_64

Code:

> lspci -k | grep -iEA5 'vga|3d'
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)
	DeviceName:  Onboard IGD
	Subsystem: ASUSTeK Computer Inc. P8 series motherboard
	Kernel driver in use: i915
00:14.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller (rev 04)
	Subsystem: ASUSTeK Computer Inc. P8 series motherboard

Intel 3570K, no external Video controller.
Mouse cursor is invisible but exists (I can click).
Problem occurs only directly after login or unlock GUI session.
Switch to text console (ctrl+alt+F1) and back almost always solves this but sometimes not.
I'm using Debian Testing for about a year and this never happened before one of the most recent system updates.
(and didn't happen for years in Mint Mate nor Ubuntu).

i still think this is a graphics problem, and related to your other issue.

the next thing to investigate would be: what sort of system are you using?
how did you install debian testing, what sort of desktop environment?

a quick web search does yield some interesting results.

well, that's why it's called testing...

fwiw, i have an intel i3 with skylake graphics, and on archlinux i could see how bugs would get better with each kernel upgrade. it's at 4.5.x now.

DEBIAN TESTING AMD64

Normally from installation media. The problem occurred after normal update.

As described: Mate Desktop

Actually it is Core i5 3570K - pretty old, very popular and widely supported.

Ok, I'll try with 4.5 soon. I see it is available now.

thanks

new info:
kernel 4.5 didn't help.
In addition I upgraded some xorg input/video packages, but not xorg itself due to critical bug in new version. No effect.

Ok, problem solved. I had to change acceleration method from "SNA" to old "UXA" in /usr/share/X11/xorg.conf.d/20-intel.conf.
Strange, since it was working perfectly with SNA for a long time.
