Connection to external monitor (TV) randomly works

moewb · 2016-05-17 15:30:13

Configuration

Video card: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV620/M82 [Mobility Radeon HD 3450/3470]
Driver: xf86-video-ati (1:7.7.0-1)
Desktop environment: Gnome-shell (3.20.2-1)

Issue

The issue is simple: when I try to connect my laptop to my TV through HDMI (on both side), it works maybe once out of 5 or 6 times.
I also tried to plug the HDMI cable into the laptop before booting it; it always works until GDM/Gnome-shell starts.
When it fails, usually the screen turns black for a while, and turns on again but the whole screen becomes tons of artefacts. It seems that the server X dies, as

sudo systemctl restart gdm

can't even solve the problem...
If I switch to a TTY, I get my screen replicated on my TV with the right resolution.

Does some has an idea of where this problem could come from?

Is there any other information I could provide to help?

I found this issue (https://bbs.archlinux.org/viewtopic.php?id=179906) and tried to disabled Dynamic Power Management as suggested, but it didn't change anything
