Razer Blade Stealth - X windows - No touchpad/touchscreen

datafatmunger · n00b Joined: 02 Apr 2016 Posts: 30

Still mucking around trying to get this machine running...

Xwindows starts up, BUT no touchpad...or touchscreen for that matter, as it, I guess should also just work.

Trying to get Libinput to handle this, followed the guide here: https://wiki.gentoo.org/wiki/Libinput ... BUT I will say I also tried synaptics, but had the exact same results...so I do suspect it's a hardware/driver issue.

lspci, lsusb output and kernel config please. Kernel config should go to pastebin as it is too large for the forum. Put your lsusb and lspci inline in [code] tags.

@Telemin - Thanks for the response!

Okay, another sunrise-point machine. You probably have an I2C touchpad, and so you need to enable the relevant LPSS drivers. Take a look at this thread where someone had very similar issues. Essentially you need to enable CONFIG_I2C_HID, CONFIG_MFD_INTEL_LPSS_PCI and possibly a few other bits, but this should point you in the right direction.

I *think* your touchscreen is the Elan 04f3:2356 device on the usb bus. For this the kernel driver CONFIG_HID_MULTITOUCH should be enough.

Good luck, keep us posted,

@Telemin - Thank you for the response. I recompiled the kernel with the options you suggested, BUT...my keyboard stopped working.

In fact I couldn't even get beyond the disk encryption password.

Okay, that is deeply peculiar. Are you sure you didn't break it by changing something else in the kernel? Usually laptop keyboards are PS/2 so that should be handled by a totally different driver and subsystem. Failing that it might be usb and would fall under the CONFIG_USB_HID driver.

Otherwise can you post the new kernel config where the kb does not work so I can see everything you changed, and a dmesg log from the kernel where the keyboard does work so I can try to work out what the keyboard actually is.

We'll get there!

Thank you again @Telemin for the response.

I went back to the previous .config, then re-enabled the items you suggested, and the keyboard works...so I must have actually enabled something I shouldn't have...anyway keyboard works...

...BUT with CONFIG_I2C_HID and CONFIG_MFD_INTEL_LPSS_PCI, still no touchpad (I'm ignoring the touchscreen at the moment).

Here is my current kernel config:

NOTE - Enabling the 2 things above, no idea why, I could not mount /boot, unknown fs type 'vfat'...this thread fixed that: https://forums.gentoo.org/viewtopic-t-714737.html

Update: Touch screen does work. Which is great, because at least now I can focus an Xterm and get cleanly out of X without an ssh reboot.

BUT...still no touchpad. Tried adding some kernel configs from this thread: https://forums-lb.gentoo.org/viewtopic-t-1038042-view-previous.html?sid=b081fc7a872b326c3f91c4330fbe60ba

Still no luck.

datafatmunger,

lspci -k will confirm that the drivers for your LPSS chipset are loading correctly.

In addition, I have found some more information on the way the touchpads are setup, so please try enabling the following kernel options: I2C_DESIGNWARE_PLATFORM I2C_DESIGNWARE_PCI you will find these in devices drivers -> I2C support -> I2C hardware bus support. This should allow your kernel to actually talk to the devices on the I2C bus and find your touchpad.

@NeddySeagoon - Thank you again for help.

Well I opted to just bake-in those items:

datafatmunger,

Pastebin your dmesg, after Xorg has started. This will show hardware issues, if any.
Pastebin /var/log/Xorg.0.log, so we can see what Xorg is doing.
Pastebin your kernel .config file too please.

What does

I also thought I would go after this PCM controller (00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC)..., thinking maybe that would help? Trying the driver in this thread: https://forums.gentoo.org/viewtopic-t-1054764-view-next.html?sid=fabd31f63280dcf124afbf2ce7b439b6 ...BUT it doesn't seem to get used so, dunno.

datafatmunger · n00b Joined: 02 Apr 2016 Posts: 30

I'm also guessing it's still a hardware driver issue, so not X...if I cat /dev/mouse0 and use the trackpad...nothing...but if I cat /dev/mouse1 and use the touch screen, I do get "junk"...idk.

datafatmunger,

I suspect that a piece of the driver 'layer cake' is missing.
All the bottom layers that show up in lspci -k are there. All the top hardware layers, like i2c, seem in be there.
That leaves a middle layer or two or a special HID device. That's all kernel.

A few things from dmesg

@NeddySeagoon - Thank you for reading ma' logs. :-P

I'm pretty deep into this issue at the moment, and feeling not nearly 1337 enough to know my I2Cs from my smbus, from my lpss...

I built probably a lot of useless things into the kernel based on this thread..., as the hardware seems pretty similar (sans the display and network adapter): https://wiki.gentoo.org/wiki/Dell_XPS_15_9550, but no luck.

It's difficult for me to tell if add/removing items is actually changing anything, as more or less the same drivers are always selected.

I then stumbled upon this Thread: https://www.reddit.com/r/Fedora/comments/46vwid/howto_fedora_23_winderz_10_dual_boot_on_the_razer/, relevant step 10. Only the git repo doesn't build...

datafatmunger · n00b Joined: 02 Apr 2016 Posts: 30

Sorry missed the 2 questions at the end ->

Does the built in keyboard work? - Yes

Exactly what make and model PC is this? - Razer Blade Stealth

datafatmunger,

[-Werror=incompatible-pointer-types] is a change to gcc. Its tightening up its specification checking.
In this case its been told to treat the warning about incompatible-pointer-types as an error. Its something is the build system doing that.

incompatible-pointer-types is generally a bad thing. If it used to work, it was luck.

That git repro is from 2014 and appears to be for a 3.x kernel. Its unlikely to work for 4.x. However it does say

Hu & of course Neddy, thank you both very much for help with this thread I own you beers.

I did try these items but they still didn't work.

I downloaded and booted the live Ubuntu 17 USB, and...it works. At least I know the hardware is still functioning.

Here is the lspci -k from Ubuntu:
https://paste.pound-python.org/show/2dbyhiimB3HoanWvjnh8/

Here is mine (I did rollback the .config a bit, it was a LONG DAY of trying 1 million things...)
https://paste.pound-python.org/show/8w4hqJoosLFbew3T6wzl/

00:1f.4...neddy already mentioned this...but not sure why it's I'm using i801_smbus...and 00:1f.2...I've selected the kernel config for intel_pmc_core...but it's not loading.

datafatmunger,

Ubuntu gives you a fully modular kernel.
What does its lsmod show?
Compare it to your Gentoo.
Ubunto probably has a lot of useless junk there too.

I mentioned the layers of a cake. The top and bottom layers are easy to find.
The intermediate layers are much more difficult.

What does Ubuntus Xorg.0.log show?
You can't emerge wgetpaste on Ubuntu but its only a script with no dependencies.

datafatmunger · n00b Joined: 02 Apr 2016 Posts: 30

Well if I wanted a big fat easy kernel...I'd just install Arch, plus I wouldn't have worry about the compile times and the systemd magic. :-P

I prefer Gentoo (this will be my second gentoo machine), and would perfer not to steal some other distribution's .config (i like small kernels)...and I'm happy to write a wiki article for the stealth if we could just get through the touchpad issue.

lsmod looks the same...between the live usb and the gentoo install.

@Neddy,

most distros have a pastebin utility nowadays. I think it is called pastebin or pastebinit in Ubuntu.
