Ubuntu drivers eating a lot of CPU. Not always but at least 50% of the times
I have actually a very slow PC because of this:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1541 root 20 0 2343424 51804 2624 S 111.9 1.4 198:49.14 DisplayLinkMana
in other words, DisplayLinkMana(ger) eats a lot of CPU. from 50 to more than 100%
I think this is an issue, that should be fixed.
