| RAOF | Sarvatt: Doh! If that doesn't fully fix your touchpad you might want to ping whot; he's under the impression that'll fix his redhat bug :) | 00:26 |

| sforshee | cnd, I'm doing some debug prints in x-x-i-s for the bcm5974 s3 problem. My assumption is that all events from the touchpad will go through the loop in EventReadHwState. Is that correct? | 21:31 |
| cnd | yeah | 21:31 |
| sforshee | okay, so here's what I see then... | 21:32 |
| sforshee | UninitializeTouch is called on the way down, InitializeTouch is called coming back up | 21:32 |
| sforshee | no events come in before I touch the touchpad | 21:32 |
| sforshee | yet it's still messed up | 21:32 |
| cnd | maybe the state is still somewhat screwed up even after uninit and init? | 21:33 |
| sforshee | that would be my guess | 21:33 |
| sforshee | so resetting num_touches isn't enough I guess | 21:34 |
| cnd | sforshee, what are you seeing when you hit the bug? | 21:36 |
| sforshee | basically most things kind of acts like I have one additional finger down, except for moving the pointer which works fine | 21:37 |
| sforshee | so a click generates a right click | 21:37 |
| sforshee | a 2-finger drag moves windoes | 21:37 |
| sforshee | *windows | 21:37 |
| sforshee | etc. | 21:38 |
| sforshee | actually the click behavior with one finger is inconsistent, sometimes I get right click, sometimes left click | 21:39 |
| sforshee | two-finger drag very consistently moves windows though | 21:39 |
| cnd | that's odd | 21:40 |
| cnd | I'm wondering if there is an issue with mtdev | 21:41 |
| sforshee | hmm, now something is wedged | 21:41 |
| cnd | here's my theory | 21:41 |
| cnd | mtdev takes untracked touches | 21:42 |
| cnd | and tries to follow touches and assign them to tracked slots | 21:42 |
| cnd | let's imagine that mtdev thinks there's a touch in the middle of the trackpad | 21:42 |
| cnd | if you then physically touch in the middle of the trackpad, it will think it's the same touch | 21:42 |
| cnd | but if you touch somewhere else, it will think it's a different touch | 21:43 |
| cnd | that would explain why sometimes it acts like there's one touch, and sometimes two | 21:43 |
| sforshee | I was trying to see if the right vs. left click correlated with where I clicked, but I didn't get a good feel for it before it wedged | 21:44 |
| cnd | sforshee, I wonder if you can reproduce by keeping one finger touching while you log out to restart the X server? | 21:49 |
| sforshee | cnd, just during the logout? or hold it down when logging in too? | 21:50 |
| cnd | just during the X server restart | 21:53 |
| cnd | once you hit the greeter you can release | 21:54 |
| cnd | then type your pw to log in | 21:54 |
| cnd | then test | 21:54 |
| sforshee | something doesn't like that very much :( | 21:56 |
| sforshee | the one time it worked it didn't reproduce the bug. but I got several hangs | 21:56 |
| cnd | hmm | 21:58 |
| cnd | what kinds of hangs? | 21:58 |
| sforshee | I can ssh in, so the system is still up, but the desktop is completely frozen | 21:58 |
| cnd | sforshee, keyboard input doesn't work? | 22:00 |
| cnd | because a stuck pointer would look like a hung system | 22:00 |
| sforshee | nope | 22:00 |
| sforshee | in fact this last time it hung before displaying the greeter | 22:00 |
| cnd | hmm | 22:01 |
| sforshee | can't switch to vt1 either | 22:01 |
| cnd | what about from your ssh session | 22:01 |
| cnd | sudo chvt 1 | 22:01 |
| cnd | sudo stop lightdm | 22:01 |
| cnd | either of those work? | 22:01 |
| cnd | sudo killall -9 X | 22:02 |
| cnd | :) | 22:02 |
| sforshee | chvt 1 doesn't work, it seems to be stick in ioctl(3, VT_WAITACTIVE | 22:03 |
| sforshee | service lightdm stop works | 22:03 |
| RAOF | I love that the X server can disallow VT switching. It makes everything so much more robust :/ | 23:33 |
