Description teuben 2001-08-04 21:11:49 UTC
From Bugzilla Helper: User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.6-3.1 i686) Description of problem: nominally either USB or PS2 will work, not both. I tried it, but was not happy that way. So, rebooted, let kudzu come up but despite that i choose to keep USB (was a bad idea) and stuck the external mouse in the PS2, X would not start and coredumped because /dev/mouse was not present (thinking it was usb, also proven by /etc/sysconfig/mouse). started X again (i was stupid) and then the machine hung. The only way to get out of this to run manually mouseconfig and tag it as PS2 again. Basically USB external and touchpad PS2 together on laptops is a problem which I'd love to solve, but don't see how yet. How reproducible: Always Steps to Reproduce: 1. put mouse in usb port 2. reboot and let kudzu select usb mouse 3. start x, it will fail 4. start x, and my machine hung, needed to powerboot 5. run mousconfig, as kudzu would not detect change of hardware Additional info:
Comment 1 Glen Foster 2001-08-06 22:41:23 UTC
We (Red Hat) should try to fix this for the next release.
Comment 2 Pete Zaitcev 2001-08-07 01:07:23 UTC
I do not see how and what I can fix here. Glen, you marked this is "SHOULD", please tell me what you want me to do. If we are asked to pull PS/2 events into HID framework, then I'd rather not do it for 7.2 (8.0 - perhaps). Too much change too late into the release.
Comment 3 Byron Miller 2001-08-10 17:39:10 UTC
I have a DELL c600 with a similar type scenerio. I have USB mouse when docked and luckily don't have the laptop open to touch the touchpad. when undocked i have to run mouseconfig again to switch to the ps2 mouse (and reboot). Is there a way to pass a parameter to the kernel or kudzu for docked/undocked profiles or something similar? docked i have USB mouse, passthrough video (which was another interesting thing to fix in the xfree86-4 config) and a scsi card.. undocked i'm on eth1 and ps2 mouse.. i have to manually reconfigure as kudzu only recognizes the changes the first time it happens.
Comment 4 Pete Zaitcev 2001-08-10 21:12:03 UTC
Thanks, it is getting clearer. If kudzu cannot detect a change, it's a bug in kudzu. In my testing it keeps detecting it indefinitely, unless you say it "Keep Configuration" once, then it goes deaf to changes. It think it is a bug that we cannot make it "unstuck". Things like putting PS/2 mouse into the HID framework are done on R&D budget normally. For instance, keyboard works exactly like you say: plug USB keyboard in and you can type ON BOTH; pull it out and you can continue typing on built-in keyboard. That work was sponsored by SuSE Labs and done by Vojtech Pavlik. In any case it's not something that I can fix easily before 7.2 goes out. Let me bug Vojtech, he might have a candidate patch - in that case we may stuff it into the first errata, or as minimum Raw Hide.
Comment 5 Byron Miller 2001-08-12 17:31:19 UTC
Basically i think kudzu is finding the internal ps2 pointing devices when i install (since i couldn't install docked because the monitor passthrough doesn't work until i configure x to use bios and extern_disp). When adding or removing the PS2 external mouse or USB external mouse (ps2 at home, USB on the docking station at work) it seems to confuse the system since both devices have different paths under /dev. If i use USB at work and ps2 was used during last reboot the HID driver doesn't seem to get loaded (kept configuration in kudzu for ps2??) and when i switch back to ps2 i have to run mouseconfig to rebuild the links to /dev/psaux. anyway to unkeep both configurations and have them noticed on boot? I have an ethernet on the docking station and an ethernet on the laptop that i use at home and at work, so i just had kudzu keep both configurations and i setup dhcp to boot on both interfaces to detect when i'm at home and work. this is impossible as it appears to be to me because there doesn't seem to be anything that will detect which port the mouse is listening on with both devices configured. Is there any known configuration where by defualt the ineternal "eraser" mouse and touchpad will work? By default i can't get x to start without an external mouse configured (no pointing devices error) is there a way i can get x to probe the inernal devices so they always work and then have kudzu or mod probe determine which external device is install. (i guess a HAL for mice in a sense..) if you have any clues on getting a base x configured to use internal mice that would be a good starting point for me to work around it. And if you can pass parameters on install to use an external display/passthrough display on a future release of redhat (or make it seemless based on detecting the popular docking stations on bootup through kudzu hehe) that would be excellent
Comment 6 Pete Zaitcev 2001-08-19 19:24:13 UTC
I think mouseconfig is the only answer right now.
Comment 7 Pete Zaitcev 2001-08-21 19:04:39 UTC
Track a SF project <http://www.sf.net/projects/linuxconsole>. jsimmons says they have a mouse driver that feeds into Input/HID.
Comment 8 Pete Zaitcev 2001-12-23 08:23:58 UTC
A considerable debate is going on about the best means to implement the workaround. Some people wish to pump events through gpm. Meanwhile, here's an elegant workaround by sct, for the knowledge base (I think it requires XF86 4.x): From: "Stephen C. Tweedie" sct Subject: Re: hotplub, usb, mice Date: Fri, 30 Nov 2001 10:36:08 +0000 > This set would make USB mice work *much* better; just plug it in and it'll > work w/o restarting X That's exactly how my laptop already works with the addition of the trivial X config section below. It's very very easy. Section "InputDevice" Identifier "Mouse1" Driver "mouse" Option "Device" "/dev/input/mice" Option "Protocol" "IMPS/2" Option "Emulate3Buttons" "on" Option "ZAxisMapping" "4 5" Option "AlwaysCore" "on" EndSection The Identifier "mouse1" distinguishes it from the primary pointer, but the "alwayscore" option means that mouse1 always generates core pointer events so you don't have to explicitly enable it with xsetpointer. The kernel does all the rest of the magic for you. It works whether or not there's a mouse plugged in when X starts. Cheers, Stephen

Same recipy, but more comprehensive: ---------------------------------------------- From: Owen Taylor Date: 07 Jan 2002 11:37:51 -0500 Subject: Better support for mixed PS/2 and USB mice Just noticed that Alex and I both had "fixed" our XF86Config in the following way, when we were helping Jonathan to do the same thing. If you want to be able to hot-plug an external USB mouse in confunction with the internal "mouse" of a laptop, instead of having Kudzu rewrite the XF86Config when it detects a USB mouse, set up both mice in the XF86Config: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Device" "/dev/mouse" Option "Protocol" "PS/2" Option "Emulate3Buttons" "off" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "Mouse1" Driver "mouse" Option "Device" "/dev/input/mice" Option "Protocol" "ImPS/2" Option "Emulate3Buttons" "off" Option "ZAxisMapping" "4 5" EndSection Then in the ServerLayout section put: InputDevice "Mouse0" "CorePointer" InputDevice "Mouse1" "SendCoreEvents" I don't see why we can't always set up our XF86Config this way. Regards, Owen
Comment 10 Pete Zaitcev 2002-06-19 18:10:29 UTC
Bill says we might need some kernel job after all; See 67032 for justification and 35215 for actual patch. Investigating.
Comment 11 Jos van den Oever 2002-08-24 09:45:39 UTC
This not entirely related but still... I've installed (null) with an external IMPS/2 mouse attached to my laptop. Upon rebooting without this mouse, the trackpad of my compaq presario 1926, which only works with PS/2 despite the up/down arrow underneath, wasn't detected at startup. I solved this by editing /etc/X11/XF86Config, it would be nicer if no user intervention after a change of pointer device was necessary. Of course hotplugging the mouse would be really fantastic and foolproof.
Comment 12 Pete Zaitcev 2002-11-04 21:05:32 UTC
The fix is now implemented in RH8.0, but it hit a little snag. If installation is done with PS/2, Anaconda uses /dev/mouse for the PS/2 part. When a USB mouse is connected, kudzu replaces /dev/mouse symlink previously pointing to /dev/psaux with /dev/input/mice. The X11 opens /dev/mouse and /dev/input/mice, but they point to the same place.
Comment 13 Brent Fox 2002-12-12 19:22:39 UTC
I'm not sure why this was assigned to redhat-config-mouse. All it does is edit the /etc/sysconfig/mouse and /etc/X11/XF86Config files. It doesn't change anything in /dev/
Comment 14 Brent Fox 2002-12-23 06:55:46 UTC
I don't know about the links in /dev, but I do know that plugging in a USB mouse into a system with a ps/2 mouse seems to "just work" in the latest tree as far as X is concerned. The USB mouse won't work in console mode until redhat-config-mouse is run so that /etc/sysconfig/mouse is configured to enable both mice. Closing as 'Rawhide'
