Hello,

I am on the most recent up to date Kubuntu system. I use this kind of graphics card:
[AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM]

After the recent updates launching firefox, thunderbird and chromium causes the screen go blank. I can't do anything except press Alt+F4. Thunderbird has become unusable. The screen goes black, I can't use the system, I can only exit the application or press CTRL+ALT+DELL and logout or reboot.
What can this be related to? Does anyone else have the same problem?

All the other applications are working.

Regards,
Richard

Just to let you know, I think I pushed my computer too close the my power sockets and there must have been some interference, now my Kubuntu is working.
Thank you for helping :-)
