Workaround for graphics issue with Kernel 4.15.0-20 on Acer Travelmate B117

Post by goetzkluge » Sun May 20, 2018 6:08 am

Sometimes I run a Acer Travelmate TMB117-M from an external SSD using Linux Mint 18.3 Mate, 32 bit with Kernel 4.15.0-20.

Standard boot: The login screen shows garbled graphics. Keyboard doesn't work well.

Workaround: Boot in recovery mode.

Additional info: I am using changed GRUB settings:

Code: Select all

#GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
#GRUB_HIDDEN_TIMEOUT_QUIET=true
#GRUB_TIMEOUT=10
#GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
#GRUB_CMDLINE_LINUX=""

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=2
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
# GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX_DEFAULT="modprobe.blacklist=ndiswrapper"
GRUB_CMDLINE_LINUX=""
I did not test the workaround with the original GRUN settings.
