[Bug 954532] New: Elantech Touchpad on Acer Aspire R11 not detected
http://bugzilla.opensuse.org/show_bug.cgi?id=954532 Bug ID: 954532 Summary: Elantech Touchpad on Acer Aspire R11 not detected Classification: openSUSE Product: openSUSE Tumbleweed Version: 2015* Hardware: x86-64 OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: robin.roevens1@pandora.be QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Installed Tumbleweed on a brand new Acer Aspire R11 (R3-131T-C56L). Turned out the Touchpad does not work. It is even not listed in /proc/bus/input/devices. The Raydium touchscreen however works correctly. I first tried Leap 42.1 on this machine but had to convert to Tumbleweed since ACPI and the VGA adapter where not correctly supported. BUT the touchpad was detected correctly and worked without problem. On Tumbleweed ACPI and VGA work correctly but no touchpad is detected. When I boot in the Leap Recovery system /proc/bus/input/devices contains this about the touchpad: I: Bus=0011 Vendor=0002 Product=000e Version=0000 N: Name="ETPS/2 Elantech Touchpad" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input4 U: Uniq= H: Handlers=mouse0 event1 B: PROP=5 B: EV=b B: KEY=e420 10000 0 0 0 0 B: ABS=661800011000003 In Tumbleweed it just is not listed. -- You are receiving this mail because: You are on the CC list for the bug.

Also no entry in journalctl when I push that button. -- You are receiving this mail because: You are on the CC list for the bug.

Then, could you install the Leap kernel (4.1.x) on the TW system and boot with it? It's available in OBS Kernel:openSUSE-42.1 repo. You can test the input device even without graphics, etc. Use evtest program (install evtest.rpm if not found). On Linux console (VT1 or so), run evtest with the input device file (as root). Something like: evtest /dev/input/by-path/platform-i8042-serio-1-event-mouse and touch your touchpad. It'll show the position, button, etc. You can test the same with TW kernel. -- You are receiving this mail because: You are on the CC list for the bug.

Now with acpi=off Xorg doesnt start up but also keeps trying starting up so I don't get the chance to log into cli as the terminal constantly flickers back to failing X. and with acpi enabled, I get a black screen during boot and can't do anything (SSH is not enabled on the laptop) I also can't boot in 4.3 anymore to disable Xorg since zypper removed that kernel during install of 4.1. How do I prevent X from starting in this state ? -- You are receiving this mail because: You are on the CC list for the bug.

I haven't found so much difference in elantech code between 4.1 and 4.3. This makes me wonder whether 4.3 would work in the input dev level. Please try boot 4.3 kernel and test just like 4.1 kernel, i.e. with acpi=off and evtest. Do you still see difference from 4.1? Also, try with normal boot (with i8042.nopnp) but test with evtest. How about this? For installing a kernel package, just run like zypper in --oldpackage kernel-*.rpm This will work in most cases without changing anything else. For recovering 4.3, run zypper again like zypper in -f -r repo-oss kernel-default supposing repo-oss is the main TW repository. For booting without X, just put "3" to the boot option, which means to boot in runlevel 3 in the old manner of sysv. Last but not least: the problem with blackscreen on Leap kernel is also interesting. For that, try to boot with nomodeset boot option. This will keep UEFI framebuffer mode without native graphics driver. -- You are receiving this mail because: You are on the CC list for the bug.

To summarize the results: - In TW: Booting with 4.3 and acpi=off results in touchpad working. evtest show events when touching the pad. Xorg however fails to start. - In TW: Booting with 4.3, acpi enabled and i8042.nopnp results in device existing but touchpad NOT working. evtest doesn't show events when touching the pad. Xorg does start correctly with accelerated VGA. - In TW: Booting with 4.3, normal boot without extra parameters results in device not being detected (AUX port disabled warning). Xorg does start correctly with accelerated VGA. - In TW: Booting with 4.1, acpi enabled and nomodeset the screen indeed does not turn black during boot. However, it seems now also using this kernel, the touchpad is also NOT detected. (warning about AUX being disabled in dmesg). Xorg fails to start. - In Leap: Booting with acpi=off resulted in Xorg starting up using unaccelerated framebuffer graphics. Touchpad working. .. So it seems to be ACPI related. I also noticed, as it may be related in some way: (just giving you this information, in case it could be useful. I don't really require investigation on these things) - Whenever i boot with acpi enabled there is no graphical splash screen displayed during boot. Instead I get a text splash with 3 strange characters in the middle instead of the 3 little squares. - When I boot with acpi=off I always get a graphical splash screen. - Strange however: When I boot a read-only snapshot with acpi enabled I DO get a graphical splash screen. - Also note: first try of Leap was using Legacy BIOS instead of UEFI: In Legacy mode Grub was displayed in low resolution, was really ugly and very very slow (characters where displayed one by one). Also booting Leap was in low resolution. ACPI enabled resulted in black screen. But also with ACPI disabled Xorg fails to start while that does work when booted in UEFI with ACPI disabled. -- You are receiving this mail because: You are on the CC list for the bug.

So, yeah, this looks more like an ACPI-related issue. Normally, this device should have been enabled via HID driver. But it failed due to some reason, as found repeatedly: i2c_hid i2c-ELAN0501:00: Failed to get GPIO interrupt i2c_hid i2c-INT33D1:00: Failed to get GPIO interrupt It implies that the GPIO description assigned to this device via ACPI doesn't exist or is wrong. Jiri, do you have any clue? In anyway, I suppose this should be reported rather to upstream, as it's a problem seen in the latest upstream. -- You are receiving this mail because: You are on the CC list for the bug.

I have too the same laptop (Acer Aspire R3-131T) and I'm using leap 42.1. With kernel 4.1 you have to pass the option acpi=off in order to boot the laptop, but there is no graphic acceleration and only one CPU core is available (touchpad works). With kernel 4.4.0 there is no need of acpi=off, but then the touchpad is not working and there are a lot of messages about the GPIO interrupt in the log: i2c_hid i2c-ELAN0501:00: Failed to get GPIO interrupt i2c_hid i2c-INT33D1:00: Failed to get GPIO interrupt So has this problem being reported upstream?

The platform we have here is an Intel Braswell which has a Cherrytrail GPIO controller. Unfortunately we don't compile in that one in the openSUSE kernel config: # CONFIG_PINCTRL_CHERRYVIEW is not set Once enabled, Linux can find the touchpad. There is still something broken with the SD card input detection (also going via the GPIO controller), but I haven't tracked that down yet. Also, once Linux can successfully detect the device, it still won't work thanks to https://bugzilla.kernel.org/show_bug.cgi?id=108481 which would have to get backported to our kernel (or we wait for stable). -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=954532 http://bugzilla.opensuse.org/show_bug.cgi?id=954532#c20 --- Comment #20 from Giacomo Comes <comes@naic.edu> --- I can confirm that after enabling CONFIG_PINCTRL_CHERRYVIEW and using the patch: https://bugzilla.kernel.org/show_bug.cgi?id=108481 the touchpad is working on my aspire R3-131T (kernel 4.4.0). The SD card has problem indeed, so if a patch for it is available please let me know and I will test it. About Leap 42.1 it would be great if not only the touchpad get fixed, but also if the support for the Braswell chip can be improved. -- You are receiving this mail because: You are on the CC list for the bug.

Once when my request is pulled and merged back to stable branch, this can be fixed, finally. -- You are receiving this mail because: You are on the CC list for the bug.

Same problem, it wasn't listed at all in /proc/bus/input/devices when it wasn't working, and when it worked it did get listed. Adding i8042.nopnp to kernel options did fix the behavior, which I am posting here just in case somebody comes across the same issue. I'm not sure but it seems like the touchpad driver was freezing Leap 15.2 on some reboots so I jumped into Tumbleweed since the hardware is fairly new, and it worked fine. I'm not sure why would this kernel parameter fix it, and I didn't check dmesg, but ok! -- You are receiving this mail because: You are on the CC list for the bug.
