Tablet mode not working on Brunch r86 k5.4 stable 20201201 #703

I updated my Elite book G5 1080 and tablet mode has stopped working. I reinstalled with Chrome OS with latest build still does not work. Reinstalled with previous version and now it is back. Thanks for all your help.

It seems there is a regression wrt tablet mode on some devices with 5.4 kernel. For now, I have not identified what's causing this but the future brunch releases will have both 4.19 and 5.4 kernel included.

If you want to try it, a test build with both kernels has been uploaded in "brunch-unstable" repository. (5.4 is the default, if you want to boot with 4.19 kernel replace "/kernel" on the grub configuration linux line with "/kernel-4.19")

I ran into a slightly different issue. Upgraded to r87 with kernel 5.4, my device is now booted into tablet mode by default, and changing the variable in /sys doesn't make any difference (to exit the tablet mode). Device: Lenovo YOGA 700

@librehat Could you try adding "module_blacklist=thinkpad_acpi" on the kernel command line ?

@ashnazir786 Could you try adding "module_blacklist=hp_wmi" on the kernel command line ?

@sebanc It was very weird so I first rebooted with kernel-4.19 and it worked fine then I rebooted again and the GRUB couldn't boot anymore. So I changed it to kernel-5.4 and so far it's been working fine?? I'm not sure what is going on but the tablet mode issue is also gone

Tablet mode worked until r86 k4.19 stable. Tablet mode does not work with kernel 5.4 4.19 on r87 stable The model is Panasonic Let'snote mx-5 Thank you

Same here on latest chromeOS rammus and latest brunch, everything works so far on my Dell 5290 2in1

If you still have this tablet mode issue could you run the below commands in crosh shell and post the output:

Also please attach a dmesg (run dmesg > ~/Downloads/dmesg.txt in crosh shell and attach dmesg.txt from your downloads folder)

@maxdojin Could you try the latest build in the brunch-unstable repo ?
