Hi ! After having a good experience with linux-2.6.11.8 under ibm t40, I decided to use it under dell/inspiron 600m.
The problem I found is that the touchpad doesn't tap properly. Under linux-2.6.10 with same debian/unstable it does... Somehow it's possible to single tap, but no way to reproduce the tap... double tap is not possible... Annoying? Any ways. For linux-2.6.10 the touchpad is detected as follows (dmsg): input: PS/2 Generic Mouse on isa0060/serio1 While for linux-2.6.11.8: ALPS Touchpad (Glidepoint) detected Disabling hardware tapping input: Alps PS/2 ALPS Touchpad on isa0060/serio1 In both cases the touchpad is detected on isa0060, but in the latest case as a touchpad and in the erliest as a generic ps/2 device. For the latest case it doesn't work, but for the earliest it does... I searched the web but I got really confused... 1) It looks like the touchpad is the one detected on linux-2.6.11.8. Can some one confirm if right? I mean, I tried to find description from dell but didn't find it, so I'm not 100% sure... 2) If the touchpad is not detected correctly by linux-2.6.11.8, then there might be a bug in the kernel but I haven't read aobut it. I really doubt this is the case. But I'm not sure. Can some one confirm? 3) If touchpad is detected correctly by linux-2.6.11.8, then I've read about a lot of stuff on the web. There are several description for fixes, but all of them point to a kernel bug. I didn't file the bug filed against any kernel though. The only filed bug is under red-hat: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=153201. The only fix that sounds to solve the problem is provided by a red-hat guy: https://www.redhat.com/archives/fedora-devel-list/2005-March/msg00304.html. Now I'm not sure here. Has someone tried the previous patch? I looked at recently 2.6.11.9 change_log, and noting shows up there fixing this. Is the bug existant under the kernel archives? Is it planned to be solved? Has some one successfully tried it? 4) There's a mention of the Synaptics touch pad driver at: http://web.telia.com/~u89404340/touchpad. However it looks like it still have problems for 2.6.11 kernels and patches are required still. Any one has tried this synaptics driver under kernel 2.6.11.8 or later succesfully? Any patches applied? OK, it was long, but I have only doubts... So far I'm sticking to 2.6.10 kernel, however I'm afraid mechanism for the touchpad is going to change any ways.... Maybe I'll have to wait for later kernel for getting this working just under kernel (no synaptics driver). If so, has any one any idea of when is it planned to introduce the fix? I read change_log for 2.6.11.9, and the fix seems not to be there, and I also read change_log for 2.6.12-rc4, and there's no reference to this problem there either... Thanks a lot in advance, -- Javier-Elias Vasquez-Vivas
