User-Agent: Mozilla/5.0 (X11; Linux i686; rv:6.0.2) Gecko/20100101 Firefox/6.0.2 Numerous google reports show failures with the synaptics_i2c.ko driver on the HP tm2t Touchsmart tablet. About a week ago it started failing completely in that the left click function disappeared after about ten minutes after boot (around 646 seconds reported in dmesg). dmesg reports 342.449861] Registered led device: psmouse::synaptics [ 342.487837] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio4/input/input15 [ 371.005403] psmouse.c: TouchPad at isa0060/serio4/input0 lost synchronization, throwing 1 bytes away. There are multiple lines of the form of the last one, throwing x bytes away. This occurs for ***BOTH*** the touchpad and a Targus USB RF mouse. Thus it was NOT a touchpad or mouse hardware failure, but a driver issue. Obviously, I've checked the "kcmshell4 synaptiks" settings to no avail. I even wrote a script to dump and reload the driver: modprobe -r synaptics_i2c modprobe synaptics_i2c su andy -c "kcmshell4 synaptiks" to run whenever the mouse died, but it doesn't fix the left click problem. I tried using yast2 mouse to select different options. No choice seemed to make a difference. I tried different versions (desktop, pae, failsafe) of the kernel. No change. There was an associated problem I call "blitzing": if you slid a finger quickly across the bottom of the pad or the keyboard (as in wiping it off) it would often crash the system to a user login screen. I thought it might be an issue with electrical static... ===== Today I used a live DVD to run CENTOS 6.0 and the touchpad worked just fine. So then I downloaded several new Kernel versions, all versions 3.0.4-43: debug default desktop pae vanilla and their FailSafe variants. **The touchpad works just fine on vanilla!!** and does NOT on the SUSE adapted variants. It has been up for over two hours now. There also has not been any instance of the "blitzing." So it would seem that there is a problem with a SUSE patch to the kernel or its synaptic driver, **predating the current version** as I just loaded 3.0.4-43 today. I *was* on 2.6.37.6-0.7 when the critical loss of a right click occurred. (There is also a screen issue with all of the kernel versions and the HP tm2t, in that you turn off ACPI for the screen to work. I'll report details on that separately, but I cannot see the screen on the "default" and "pae" 3.0.4-43 versions, so cannot confirm that the mouse/pad does not work on them, but vanilla definitely DOES work. (There is also an issue with the wifi driver on the current version, again, I'll report separately - it works fine, but the led is alternating between red and white about twice a second... (And bluetooth still doesn't work...) I'll be glad to help in any way. I would love to have pad, screen, and bluetooth working on this machine. Like some people I know, it is lovely to look at but rather worthless if you can't get it to work... :-) Let me know how I can help further. Best regards, Andy Lavarre alavarre@gmail.com Reproducible: Always Steps to Reproduce: 1. Run any version of kernel except vanilla 2. Reboot and select a version of the kernel OTHER than vanilla 3. Actual Results: Both a Targus USB RF mouse and the HP tm2t touchpad move the cursor and can register a right click, but there is no left click function. Additionally, there is an occasional "blitzing" if moving the cursor rapidly that crashes the session to a user login screen, Expected Results: The mouse should be stable, no blitzing, and having the left click function correctly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
