Don't worry about being picky; I began life as a mathematician (B.A., 1961), though I changed fields radically soon after. When I switch the peripherals to another PC, or use a tablet cabled to the same (my only) router, I can ssh -Y; but I don't really know anything about using that -Y. When I switch the peripherals to the problem machine, I get almost normal-looking displays till I grab the mouse. Then fine white lines run all across, horizontally; after a moment, the lines increase, so that the display is useless unless you recognize what is behind the veil. After I log in, the veil gets so thick that I can just perceive a gray band across the top, and the rest of the screen blue. But the mouse cursor is plain and moves well. Ctrl-Alt-Backspace does nothing afaict, but Ctrl-Alt-Delete does make it reboot. On another PC behind the same (and only) KVM switch, and also on the tablet, I get : [btth@Hbsk ~]$ startx xauth: file /home/btth/.serverauth.1661 does not exist X.Org X Server 1.13.3 Release Date: 2013-03-07 X Protocol Version 11, Revision 0 Build Operating System: 2.6.32-358.2.1.el6.x86_64 Current Operating System: Linux Hbsk.localdomain 3.8.9-200.fc18.i686.PAE #1 SMP Fri Apr 26 13:01:35 UTC 2013 i686 Kernel command line: BOOT_IMAGE=/vmlinuz-3.8.9-200.fc18.i686.PAE root=/ dev/mapper/vg_hbsk-lv_root ro rd.md=0 rd.dm=0 rd.lvm.lv=vg_hbsk/lv_swap SYSFONT=True KEYTABLE=us rd.lvm.lv=vg_hbsk/lv_root rd.luks=0 LANG=en_US.UTF-8 rhgb quiet Build Date: 17 April 2013 04:49:59AM Build ID: xorg-x11-server 1.13.3-3.fc18 Current version of pixman: 0.28.0 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.
