I upgraded my laptop (IBM ThinkPad T20) yesterday from a perfectly happy 7.2 installation to 8.0 (using the ISO images released yesterday), and now the internal pointer, which has always been detected as a standard 3-button PS/2 mouse, is gone. Any attempt to use it (gpm, X, cat) gets me a "/dev/mouse: No such device" or "/dev/psaux: No such device" error. /proc/interrupts contains no item at interrupt 12 (where psaux used to be). /proc/misc contains the line "1 psaux", so I know I have support in the kernel (like MandrakeSoft would release a kernel without mouse support anyway!). harddrake and kudzu claim there's no mouse. A USB mouse works (if I change the link at /dev/mouse to /dev/usbmouse). This is NOT a BIOS or hardware issue: if I reboot into Windows, or if I boot with 7.2 rescue disk and type "cat /dev/psaux", the internal mouse works. The installer does not detect, nor will it use, the internal mouse. I had to use the keyboard to get it to work. This is really awful and frustrating--my machine is unusable and I'm in Windows now. In eight years with Linux, I've never had the mouse not work before. :-) ---- Trey Harris formerly of UNC Academic Technology Now with VA Linux Systems, New York region Secretary of SAGE -- The System Administrators Guild (www.sage.org)
