Installation Instructions for the CFD-Lab at the University of Alberta

Check out my Installation Instructions, which I use for my personal computers and the ones in my university research lab.

openSUSE Leap 15.1 on Lenovo Thinkpad Yoga Tablet

openSUSE Leap 15.1 supports the Thinkpad Yoga Tablet with touchscreen out of the box without any problems.

Disable Touchscreen

When using the pen for drawing or writing in Xournal or in Inkscape, the capacitive touchscreen gets in the way, because it moves the pointer every time your hand touches the screen. To disable temporarily the touchscreen, you need to install the package Xinput. Then run xinput in the terminal and find out the id number of the touchscreen, e.g. 9.
To disable temporarily the touchscreen, keeping just the stylus pen active, run xinput disable 9.
To re-enable the touchscreen, run xinput enable 9.

Restoring Grub2 in openSUSE

If the boot loader Grub2 did not install correctly, you can restore it as follows.

Using the installation DVD, boot into Rescue mode and login as root.

To confirm which disks are available and which partition is bootable:
fdisk -l
Mount the partition containing /boot, say sda1:
mount /dev/sda1 /mnt
or in case of RAID1 array, say md126:
mount /dev/md126 /mnt
Then mount the devices under /mnt with:
mount --bind /dev /mnt/dev
Now change root and mount the other directories (prompt will change to Rescue:/>):
chroot /mnt
mount /proc
mount /sys

If you need to regenerate grub.cfg, then:
grub2-mkconfig -o /boot/grub2/grub.cfg

Finally, install Grub2:
grub2-install /dev/sda
grub2-install /dev/sdb (in case of RAID1)
exit
reboot
