Hi, sorry for the double-post, but I do not know if this is 64-bit specific, as I do not have 32-bit intsallation to test. Anyway: SuSE 10 x86_64 kernel 2.6.13-15.8-default xorg - 6.8.2-100.2 ati prop. driver - 8.22.5-x86_64 (tried 8.21.7 - same problem) videocard - ATI X800 - ExpressPCI KDE - 3.5.1 Level "a" The problem: Using the switch user option of KDE to start a new kdm for a second user to login works OK, The user can login. But if then I try Ctrl-Alt-F7 to return to the other session, or when I close the new session, or if I switch to virtual terminal (Ctrl-ALt-1..6), and try to get back to any X one (Alt7-8) it badly hangs the machine. No remote access either, so I can not kill the X server. Looks like the problem is with the ati proprietary driver, as if I uninstall it and use the generic one, everything works just fine. Do someone have such a problem? Is it isolated only to the 64bit version, or it happen with the 32 bit as well? Any suggestions how to solve/or at least debug and try to solve the problem? ATI's site is horrible, so before I even try to deal with them, I'd like to receive as much as possible information. Any experience/opinion is welcome. Cheers -- -- Svetoslav Milenov (Sunny)
