Lenovo ThinkPad Troubleshooting

ThinkPads with Intel HD 3000 graphics

Several ThinkPad models have Intel HD 3000 graphics, including the T420s and the T520. Some users with these laptops have experienced random reboots, which were solved by adding i915.enable_rc6=0 as a kernel parameter to GRUB_CMDLINE_LINUX in the file /etc/default/grub in dom0.

Instructions for getting your Lenovo Thinkpad X201 & X200 laptop working with Qubes/Linux

For being able to boot the installer from USB, you have to disable VT-d in the BIOS. Enter the BIOS by hitting F1, go to Config - CPU and then disable there VT-d.

After the installation, you have to set a startup-parameter for Xen, to be able to activate VT-d again:

  1. Open a terminal in dom0
  2. Edit /etc/default/grub
  3. Add to the line GRUB_CMDLINE_XEN_DEFAULT the setting iommu=no-igfx, save and quit
  4. sudo grub2-mkconfig --output /boot/grub2/grub.cfg

Then reboot, enter BIOS and re-enable VT-d.
