Harold: Until this GoBack problem occurred, I was using XWin -unixkill -emulate3buttons -clipboard -rootless & wmaker &
I also used a few xterm commands, with very good performance: xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 80x84+91+0 -name left & xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 80x84+592+0 -name center & xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 80x84-0+0 -name right & xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 250x84-0+0 -name large & After I installed GoBack, I hit the terrible/impossible performance. I found that XWin -unixkill -emulate3buttons -clipboard -multiwindow & and with even 1 or 2 xterm windows was just a bit better, but still miserable. I tried your suggestions: XWin -engine 1 -unixkill -emulate3buttons -clipboard -multiwindow & XWin -fullscreen -emulate3buttons -clipboard & with just one xterm window, but these seem just as slow. (The fullscreen would not be so good for me as I often need multiple windows.) I disabled GoBack, rebooted as required, and I'm now running XWin -unixkill -emulate3buttons -clipboard -multiwindow & just fine. I noted that with or without GoBack my browsers and other PC applications seemed to work fine. Of course, when I brought up any XWin tool, all performance was degraded due to the load on the System. I appreciate your trying to help. Thanks. Lester : Lester, : : Lester Ingber wrote: : : : Harold: : : : ... interesting that you should ask about the hardware.
