I have a Pentium II 450 MHz machine with 512 MB RAM and 40 GB Harddisk. It has a AGP Riva TNT2 32MB Display Card, US Standard Keyboard and a 2 Button PS/2 Mouse. X Version - XFree86 Version 4.2.0 / X Window System (protocol Version 11, revision 0, vendor release 6600) Release Date: 23 January 2002 I have installed Mandrake 8.2 from the CD and during installation the mouse works perfectly fine during installation process. Once the installation is complete and when I startx from command prompt, the system freezes when I move the mouse. At that point the keyboard is also locked and i am not able to even do a numlock or a caps lock. If I start X and ensure that the mouse is not touched, I am able to navigate with the keyboard. If I use the mouse, the system freezes. I suspected problem with mouse and I have tested with another one. I suspected problem with distribution - so tried RH7.2 and ASPLinux7.2. Both are similar - mouse works fine during installation (From ISO CDs) and once I startx after logging in, the system freezes. If it is a hardware problem, then my reasoning is that the mouse should not work during installation as well. I have tried it with gpm enabled and disabled. I have tried different types of mouse including wheel mouse. I have tried all combination in mouseconfig and Xconfigurator. I am not able to see any error in the XFree86 log found in /var/log. I have tried KDE, ICEWM - both have the same problem. Can any one give me an idea of what could be wrong? I have been grappling with this problem for last 2 weeks and searches in google/user groups dont help me much. Thank you, Kind Regards, Balajee Shrikanth
