Comment 15 for bug 1851340

Hi Po-Hsu Lin,

I have done simple verification with latest Ubuntu Kernel (on 19.10 install):

cat /etc/*-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=19.10
DISTRIB_CODENAME=eoan
DISTRIB_DESCRIPTION="Ubuntu 19.10"
NAME="Ubuntu"
VERSION="19.10 (Eoan Ermine)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 19.10"
VERSION_ID="19.10"

PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=eoan
UBUNTU_CODENAME=eoan

Installed lastest kernel via:
# Ubuntu Kernel PPA info
ppa_host="kernel.ubuntu.com"
ppa_index="/~kernel-ppa/mainline/"

$ uname -a
Linux green 5.4.6-050406-generic #201912211140 SMP Sat Dec 21 11:43:01 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I can confirm that with 5.4.6 that the cursor is once more working ok.

In fact now that I have tested with this kernel I think I will do in place update on this machine to focal and use it to test some other new upstream inclusions targeted for Focal Fossa 20.04 LTS.

Please let me know if you want a more complete test, as this was a pretty simple one and I have not validated anything beyond working cursor, both from console (physical) and via remote (X11VNC).

Regards,

John.
