Hello All,

I just bought a new monitor for my laptop and have some issues with it.

I had another monitor before, 24 inch samsung, had no problems with the gnome functionality at all, everything was working perfectly. Today I bought a new dell 23 inch glossy monitor. (I gave the samsung away)

The picture is amazing but I noticed that gnome is not working as smoothly as before. Minimize/mazimixe of windows is choppy also youtube videos are the same.

I did not upgrade anything before/after switching the monitors.

System and os:

I did not use the nvidia on linux before because there was no need. I installed the nvidia-detect package and it saw my nvidia gpu. I will install nvidia-glx now and reboot. I don't know if I should enable it from xorg.conf or sue bumblebee.. what do you recommend ?

Thank you
