https://bugzilla.novell.com/show_bug.cgi?id=327517#c21 --- Comment #21 from darren winter <sgt-d@sodpit.com> 2007-09-25 08:21:57 MST --- i ended up with a black screen and the X mouse pointer on screen, and i got to see the bottom .25 inch of the kde splash screen. that "nodeadkeys" problem (bug 327017) prevented me from using ctrl+alt+backspace to kill x or to switch over to tty1 to get to text mode to manually fix it. anyway, i've been thinking about this a lot this morning. i don't need to see if sax2 is working correctly or not, i know that it is writing an xorg.conf file that should work. my problem is specific to the mouse and, for sake of time (10.3 final is only 9 days from now), i would like to focus on manually adjusting xorg.conf instead of using sax2 to generate new config files each time. every time i attach my xorg.conf files i am doing it the way you have been asking (using sax2), and it has been defaulting to fbdev which you have pointed out is slower. i never use sax2's defaults, and i have never used fbdev - so that is not what is causing my problem. in my opinion this mouse lag (in my case) is not related fbdev (since i never use it) and it probably isn't "nv" although i can easily switch to that to test it if needed (tonight), and i know it isn't "nvidia" which is all i ever use. what i am trying to say (and debug) is that when i use the "evdev" mouse driver with "nvidia" (and possibly "nv"), the mouse is almost impossible to move during heavy load... i litteraly can barely move it in a 1" or 2" radius, at the very mose. when i switch the mouse driver from "evdev" to "mouse", there is still some mouse lag during heavy load, but it is at least sufferable, i can still do things and i can freely move the mouse all over the screen even though it is a little jerky. so, everything aside from sax2, here is what i have been playing with... this is what i am using currently in 10.3 rc1, and it seems "ok": Section "InputDevice" Driver "mouse" Identifier "Mouse[1]" Option "Protocol" "explorerps/2" Option "Device" "/dev/input/mice" EndSection this is what i was using in 10.3 alphas 1-7 and betas 1-3 and would probably work the same in rc1: Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection this is what was setup after a fresh installation of rc1 and it is laggy as hell during heavy system load: Section "InputDevice" Identifier "Mouse[1]" Driver "evdev" Option "Buttons" "20" Option "InputFashion" "Mouse" Option "Name" "Logitech USB Gaming Mouse" Option "Protocol" "event" Option "SendCoreEvents" "on" Option "Vendor" "Sysp" Option "ZAxisMapping" "4 5" EndSection -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
