Hi,
I collected some extra information for this problem. Please see: .xsession-errors for a newly created account: http://pastebin.com/5dsQpYLU I've mentioned that we created a new account (hence running with system default) but the lowfat client still got problems. The above one is the .xsession-errors in the home directory. Xorg.7.log for abnormal client: http://pastebin.com/Y4AC0gCP The above one is the Xorg.7.log when booting lowfat client and logged into KDE. Xorg.0.log for normally run kubuntu 13.04 on the same machine: http://pastebin.com/RRyydjSY We used Kubuntu 13.04 which was installed in the hard drive. It could run normally, and this is the normal Xorg.0.log. I have no idea where I should find the problem. Please help me with this. Thanks, Franklin
