Hi, I don't know if this is related to xmonad, but it's worth a try :) I use the rxvt terminal. On the primary monitor it works fine, but on the second and third monitor it lags like hell. When I press tab for tab completion it takes sometime 1-2 sec. to complete, where the same thing takes no time at the primary monitor. Does anybody has the same problem with xmonad? I used xterm before and I think that there were not such an issue with xterm. My config: kernel: 2.6.37-rc4 xmonad: xmonad-0.9.1 xmonad-contrib: 0.9.1 I think that problem could be connected with one of these 3 poss.: - graphic driver: I'm using the open source radeon driver - rxvt: I don't think that it is rxvt related. Rxvt shouldn't do any difference on which monitor it is used. - xmonad: Xmonad is what provided the 3 workspaces which I see at the same time. Thats why I think that is is realted to xmonad.
