Mouse cursor offset from pickpoint
Last modified: 2005-09-20 12:45:18 UTC
I have found that several times, what I thought was nonresponsive buttons, was in fact that the mouse cursor was offset from the pick point. I am not sure which way the X & Y axis really go, but if we for the exercise assume that the top left corner is 0,0 and the bottom right is screenheight,screenwidth, then the offset has always been positive in both x,y by what I guess 100 or so pixels. When it happens, it appears as though you can't get to the main Suse menu as the mouse cursor stops before it reaches the top left corner. In reality the actual clicking point is in the top corner. Interestingly, when the cursor is brought to the bottom right corner, the offset is reset to zero, as though the cursor is bound by the bottom corner and forced onto the pick point again. It then remains with no offset. I have not yet worked out what triggers the offset. The physical mouse is a Logitech Optical USB mouse.
I am able to replicate this bug on Gentoo Linux after using XRandR extension (using gdm, logging out from session with one screen resolution and logging in to session with another screen resolution defined in gnome-display-properties) with ATI Rage 128 graphic card with opensource drivers (Xorg ati + gatos patch). Can you be more specific, when the bug occur and which graphic card do you have? I guess that it can be problem of X driver or XrandR itself.
Sure, no prob. I have seen it three or four times now. Once more since my report. The offset is not at login, but just happens at some point without doing any changes to resolution or other display parameters. I just installed OpenSUSE 10 beta 1 yesterday, and I have not installed any patches or driver updates. My physical card is an ATI radeon 9200, which Suse reports as Device: ATI RV28 5964
CC'ing X guys to see if they have any ideas
Created attachment 48547 [details] hwinfo see line 55, 67, 68. Why are 3 mice detected in the hwinfo output even though there is only one USB mouse connected? Note there Logitech Quickcam Orbit (USB) when first detected had Hotplug pop up request to configure a Logitech USB mouse and may think this camera is a mouse. The camera is not functional (seperate bug report already submitted).

This has not happened to me since Beta 1, and I have since been using Beta 2, beta 3 and now RC1 on the same hardware.
