Since the upgrade to Ubuntu 18.04 (from 17.10) I started experiencing huge performance issues with video playback, both using VLC and the browser (Youtube).
The problem gets more apparent the higher quality the video is (starts at 480p, 1080p is completely unwatchable). The video is choppy to say the least.
I had no such problem using Ubuntu 17.10.
I wonder if there's someone who also had same problem and found a potential cause and perhaps a solution?

UPDATE:
It seems that it's a general issue with hardware acceleration / rendering not enabled / recognised / working.
The things I have tried so far:
Reboot.
Add xorg.conf configuration file with:
Section "Device" Identifier "Device0" Driver "radeon" EndSectionReinstall
xserver-xorg-video-radeon.
None of these things had any effect unfortunately.

This bug is worth a look at.
https://bugs.launchpad.net/ubuntu/+source/nux/+bug/1767468
The system is looking for unity support, doesn't find it (because the tool that checks for it has been remove) and so disables hardware.
Worked for me anyway.
Edit: issue the command
sudo rm /etc/X11/Xsession.d/50_check_unity_supportthis has been reported as a successful workaround to the issue.I've encountered same issue. Only available renderer was llvm.
After lot of googling I realised, because of different bug,
I put
nomodesetinto grub (/etc/default/grub) in the lineGRUB_CMDLINE_LINUX_DEFAULTIn my setup the machine works without this parameter just fine.
Check, if there is parameter
nomodesetin grub and remove it.Try if it helps.
