When I get off the train and at my destination I will try this on Ubuntu MATE and reply back thanks again.
I modified the grub.cfg file. I now have this message: error: you need to load the kernel first.
If I insert the line after the first initrd (under linux /boot/vm[…] I get a kernel panic.
I also tried:
linux /boot/vmlinuz-5.2.0-15-generic root=UUID=8267d56c-137c-4cf8-b97f-272cd5f079a5 ro splash $vt_handoff
initrd /boot/acpi_override_23
initrd /boot/initrd.img-5.2.0-15-generic
The system boot, but no touchscreen.
Ok, new attempt based on this.
Edit /etc/grub.d/10_linux
. Search for initrd
and you should see a line initrd ${rel_dirname}/${initrd}
. Above that line, add initrd /acpi_override_23
like this highlighted line. Also, you should not need to prepend /boot
to the initrd.
Then, rebuild grub.cfg
proper with sudo grub-mkconfig -o /boot/grub/grub.cfg
and restart.
If this doesn’t work, I’ll find a way to install Mate (maybe on a USB stick) and work from there.
I tried with /acpi_override_23 : file not found
With /boot/acpi_override_23 : system boot, but no touchscreen.
Here is the lines:
EOF
fi
sed “s/^/$submenu_indentation/” << EOF
initrd /boot/acpi_override_23
initrd ${rel_dirname}/${initrd}
EOF
@petem Is it working for you?
Sorry my journey was lengthy and I got unexpectedly delayed.
OK so heres what I’ve tried.
- Extract the CPIO file:
cpio --extract < ./acpi_override_23
- Copy the result to
/boot
:cp kernel/firmware/acpi/dsdt.aml /boot/fixed_dsdt.aml
- Create
/boot/grub/custom.cfg
to containacpi /fixed_dsdt.aml
I realised that /grub/grub.cfg is a dynamically generated file (as it tells you this when you open it)
the config is generated from /etc/grub.d as Josh correctly identifies.
cd /etc/grub.d
sudo nano 10_linux

sudo reboot
No longer get any errors on boot it loads ubuntu mate straight to enter password prompt
but I do not have any touchscreen at all.
NB: I should add that on both options I tried extracting CPIO as mentioned then copying to /boot
and I also did without extraction i.e Josh raw downloaded file and copied to /boot
It appeared to make no difference.
Just to make sure we’re all on the same page: is this everyone’s first attempt at getting this override to work with Ubuntu/Ubuntu Mate/grub or was the touchscreen working with Peter’s original acpi_override
file in previous BIOS versions? I’m trying to determine if this is simply a loading issue or something with the generated cpio image.
@petem - Could you execute dmesg | grep DSDT
and paste the output here with the grub configuration that seems to have loaded the override cpio?
This is my first attempt at getting Touchscreen to work. I had not got round to doing original PeterCxy fix before upgrading to 0.23.

This is mine. I feel like the CPIO image is just not loading for you guys or not loading first. I’ll dig a little deeper this evening.
I also tried this way, no more success:

You might want to look at this:
https://wiki.debian.org/OverridingDSDT
If I understand correctly, we can’t use the workaround without recompiling the kernel?
Guys, to my regret none of the solutions here helped me
I’ve got BIOS 0.23, Arch Linux with kernel 5.2.14 and GRUB 2.04
What I’ve been trying (every try with fresh grub.cfg):
- added “initrd /boot/acpi_override” record in grub menu before real initrd. No messages related to ACPI override.
- added initrd /boot/acpi_override /boot/initramfs-linux.img. Did not boot at all, hangs right after the GRUB message “Booting Linux…”
- extracted dsdt.aml file from acpi_override and tried to add “acpi /boot/dsdt.aml” before linux command entry in grub.cfg. The same effect as above.
- tried to move the “acpi …” line after linux command entry. No ACPI override applied.
Does this thing work for BIOS 0.23 and GRUB for someone? If you’ve managed to do it then please share your wisdom. Along with grub.cfg please Thank you.
Wish I could help @naquad - But I gave up after hours of messing with grub.d and trying to load the acpi override. I agree’d with Josh’s summation grub sucks or in my words is shit and it was simply not loading or not loading first. I believe arch and bios 0.23 works on systemd. I think this is what
@joshwiththegoodhair is using?
Could touchscreen work if we replace grub with systemd on debian/ubuntu derivatives?
It’s entirely possible, but I’m not that good with Linux to know exactly how to do so.
I use Ubuntu MATE / Xubuntu primarily for emacs / org-mode and LaTeX / Biblatex & TexLive stuff and even that its a steep learning curve and I’m fairly new at it sorry.
For the sake of testing I’ve moved from GRUB to systemd-boot with acpi_override for BIOS 0.23, now I have those magic lines:
[ 0.017282] ACPI: DSDT ACPI table found in initrd [kernel/firmware/acpi/dsdt.aml][0x28dc3]
[ 0.017343] ACPI: Table Upgrade: override [DSDT-ALASKA- A M I ]
But there’s no Goodix Touchscreen device at all and system boots only 1 time of 5, it stalls after “SHA256 validated” message
After booting Windows and then booting to Linux it boots 100%. But kworker/0:2-kacpi_notify process does 100% load on 1 core and still no touchscreen. Hence I suspect that version for BIOS 0.23 is not actually working.
In any case this is a huge red flag for me as touchscreen is essential for a device like P2 Max as touchpad here is very small and inconvenient.
I’m thinking we should officially request GPD company to fix this problem for us as they’ve also stated support for Linux (GPD P2 Max: The world's smallest Ultrabook | Indiegogo update at Jul 31, 2019 • 10:31AM) so its time to provide some Also it’ll be interesting how will they fix it in Ubuntu MATE that’s announced for October.
P. S. There should be absolutely no custom kernels as solution to this problem. Those dark times passed years ago and I don’t want to manually update kernels.
Sorry guys for my delay. It’s been a bit busy with work lately.
@naquad - Are you using Xorg or Wayland?
I’ll have some time later today, and I’ll work on installing Mate on USB stick so that I can help get this override loading.
Xorg. And MATE will get updates from GPD somewhere in October according to their update at Indiegogo.
I’ve started looking into kernel patch by @PeterCxy and thinking to make it a standalone custom driver: https://www.reddit.com/r/GPDPocket/comments/cuqb6x/on_the_issues_of_the_touch_screen_of_gpd_p2_max/f0c3iea/?context=3 This way no kernel patching needs to be done.
Considering how much issues with BIOS GPD is having I really doubt we’ll have some BIOS level fix in the nearest future.
Honestly, the easiest way is to just preload the proper CPIO image - this prevents the need for any kernel or driver package changes that need to be maintained. The only time that CPIO image would need to be updated is if the BIOS changes.
I’m unsure of what the issue is in Ubuntu, but I’m installing it now to work through it. The end result should be a few lines of grub updating that should persist through kernel updates and whatnot. No custom kernel. No custom drivers.
