While things got better with the second card disabled, emacs running in X Windows is still a little sluggish. However, running it in no window mode (emacs -nw) and No-X mode (emacs-nox) works great - things are snappy.

The nvidia drivers and/or x windows appear to be the culprit. Things improved when I disabled one of the two nvidia cards so now I'm only running two screens on a dual head card and have disabled the second nvidia card which powered the third screen.

I did a new install -- I formatted everything except the /home partition.

gedit appears to be ok, but I did notice that if emacs is slow when it's in maximized/full screen mode -- it's ok when it's only taking up part of the screen.

2011-11-17 23:35:25 -0500 asked a question emacs running slow on Fedora 16 and nvidia

I upgraded from Fedora 14 to Fedora 16, and emacs is running painfully slow.

Emacs is slow to open, and there is a lag when moving the cursor position, opening files, and searching within frames.

Fedora 14 was fine, and all the hardware is the same. This is with a 3.1 kernel with the latest nvidia drivers on a three-screen display.

I switched to XFCE thinking Gnome 3 was the culprit, but the lag remains.

Are there issues with Fedora 16, the 3.1 kernel, and/or nvidia drivers on multihead displays? Or where else should I be looking?
