Debian 9 XFCE 64 bits - Screen flickering

Postby MatiasBarrios » 2018-02-18 00:16

So I finally bought an I5, 8 GB RAM and a 500 GB SATA PC to get Debian running as smooth as possible. The same has a Intel integrated Video Card.

Everything went excellent, the installation was super fast and easy and the overall experience is good ( I have tested for only two days though and the only problem I did have is that I attempted to install Chrome ( not Chromium ) and the PC entirely rebooted... wtf?!! ), the package was corrupted and I did not want to have a headache with that so I just deleted it and continued using Firefox.

But thats not why I am here. I am here because there is some flickering on the desktop and I dont know how to fix it. I googled a little bit and foudn that many people have/had a similar issue ( some part of the screen goes black for a brief period of time, really short, but enough to make it perceptible ) but those post are from 2016 and before. I am posting this as I have the hope that someone would have found a straight forward way to correct this.

This is the first time I used Debian and other than that, it has been a really pleasant experience, so this is a real bummer.

The flickering occurs most of all when some window lost focus and another one gets it, as well as when I start typing somehtign or I click on an input box.

Im sorry I am not able to paste some of my system details/logs here as I am not at home right now, but being as this is an issue spread across so much different distros and also so old, I really hope someone can give me some advice here.

Thanks in advance!

I just downloaded the deb package from their official page. Then I installed it and once it was done Syanptic started throwing an erron stating that package was broken ( although Chrome itself was working fine ) so I decided I did not want a headache further down the road so I removed it. And on the middle of the removing process the entire pc got frozen and it rebooted on its own. After rebooted I opened Syanptic and got a message I should run a command before continuing on the console and everything got removed correctly.

Why do you ask may I know?

Im asking because you said you had problems with Chrome, and some people here are magicians when it comes to installing/removing packages :mrgreen:

I always used gdebi to install Chrome and had 0 problems.

Recent Intel graphcs (last 18 months or so) can require the firmware-linux-nonfree package be installed to get the graphics working correctly. You can get an idea of what you have by installing inxi and giving us the result of

Code: Select all
inxi -G

XFCE's compositor is rubbish, have you tried disabling it?

I read you cannot use Netflix on Chromium. If thats true te n there you have a deal breaker and a reason for using it instead of Chromium

No I have not. Can you tell me how to do it? For what os worth, if there is some situation where the flickering happens is when I type in a document on Kate editor. But it also happens all across the DE but less.

In xfce settings, just browse all the settings at the top and you will find it.

Took me literally 2 seconds in google.

^ so does it work now?

it does not seem to be impossible with firefox.
it does not seem to be impossible with chromium.

anyhow, for me it is a dealbreaker to a) install closed-source software, and b) let a commercial, quasi-monopolistic entity perform intrusive & potentially destructive actions on my machine without even informing me about it.
this goes for google software itself, but also for its installation.
latest example.
