I don't really know, i installed the ssh server not so i can test this. but the last 'crash', the xserver was not possible to work on it any more, just seeing horizontal stripes instead of a picture, let me go back to the console and dmesg gives now additional: [29361.912198] nouveau E[ PFIFO][0000:00:0d.0] CACHE_ERROR - ch 1 [Xorg[1029]] subc 4 mthd 0x0188 data 0x80000003 [29361.912206] nouveau E[ PGRAPH][0000:00:0d.0] ERROR nsource: ILLEGAL_MTHD nstatus: INVALID_STATE BAD_ARGUMENT PROTECTION_FAULT see the full dmesg: http://ubuntuone.com/5rZQABeUirzvxUSIDhWTcY After that i made a reboot, because a 'sudo service lightdm restart' does something strange: I have an additional LightDM User there, which is not there after reboot.... - but thats another problem. :) Martin
