Full Version: C860 keyboard stops responding problem
OESF Portables Forum > Everything Else > Archived Forums > Distros, Development, and Model Specific Forums > Model Specific Forums > Sharp Zaurus > Cxx0 General discussions
Occasionally the keyboard will stop responding. Usually after I have a lot of programs loaded, so maybe a memory problem? A reboot fixes this, but I was wondering if anyone else has seen the problem and knows a better way to get the keyboard going again.

I'm running Sharp's Rom.
My 860 would freeze when I tried to view an SD card full of pictures from my camera. Fortunately, I have the Cacko 1.21b rom with memory management app running. I created a 32M swap file on my CF card and no longer have any problems.

I would try creating a swap file on an SD or CF card manually, or better yet, flash to the latest Cacko ROM.

Similar to you, I have problems with my SL-C860 keyboard not responding. I have Cacko Rom 1.21b (I recently installed the 1.21b hotfix, after uninstalling the 1.21a hotfix).

Before I installed the hotfix b, I noticed a few times that the keyboard would die, normally after unsuspending the Zaurus. This was fixed every time by rebooting.

I thought I'd address this by installing the b hotfix. Now I've done that, I've only had the keyboard behave itself once. Now, every time I boot up the box (reboot it or shutdown -r now it) the hardware keyboard doesn't work.

You'd think this might be a hardware problem, but I'm pressing the Home key to unsuspend it/boot it up, so that indicates the home key is working fine. Also note that the jogdial and cancel/enter buttons on the case-side all function fine.

I uninstalled keyhelper, thinking that that might help fix the problem, it didn't. I've rebooted the Zaurus multiple times, and still the problem is there. Is this a problem with Cacko 1.21b and the 860?

Does anyone have suggestions for investigating this (I didn't notice anything in /var/logs/dmesg), or advice for reinitialising the keyboard? Please pass your help on, before I am forced to nand restore my last backup.

I run Cacko 1.21b on my c860 and have never had a problem with the keyboard. I don't think this is a problem with the ROM.
I agree, never ever had this issue - memory hogging the Z or not.
I've had my c860 6 days and my keyboard has never worked. Strangely, if I press the Home/Power key when its off the unit powers on but then the keys will not function. I've made no modifications to the unit. I ordered it through Dynamism and seems to function flawlessly in every other way.

I've had this problem recently since upgrading to Cacko 1.21b, on resuming from suspends

In my case, it appears to be related to having a Swap file created on SD card. If I disable it, and reboot, the problem disappears. I think this is an artifact of my SD card (or the mmcda driver...) since I also occasionally get my SD card remounted read-only after suspend/resume.

OK. Well I did have one recurrence but that was *definitely* a problem with libSDL after running Scummvm & exiting. That got fixed by re-running Scummvm and closing it nicely (instead of killing the process....)

The keyboard froze on me today on resuming from suspend (pdaXrom 1.1.0 "Kathrin" RC3). I had an Ambicom WiFi card inserted. Now, I remember reading something about this (or similar?) problem being solved by moving a cardctl (?) command by a line or two in some script. But I can't find that page anymore... Does anybody remember it? Thanks much in advance!
