[Bug 1396379] Re: installer uses first EFI system partition found even when directed otherwise

[Vlad Tudorache]

I've encountered this bug today (2022-05-20) on Debian 11 and Ubuntu 22.04. 
Configuration:
Samsung SSD 500 GB as /dev/sda
- EFI System Partition
- MSR
- NTFS (C:)
- Recovery
Toshiba HDD 2 TB as /dev/sdb
- 1,9 TB NTFS (D:)
- 512 MB (/dev/sdb2 -> /boot/efi) 
- 2 GB swap (/dev/sdb3)
- 64 GB ext4 (/dev/sdb4 -> /)
It seems that even after selecting /dev/sdb2 as /boot/efi mount point to avoid 
tampering with the Windows boot loader's location, the installer mounts 
/dev/sda1 as the EFI partition. So the bug is still there and, for me, it 
happens also on Debian. This isn't a big problem for me, I've built the PC 
myself, I know how to use efibootmgr. What about a non-technical user?
Is it really a GRUB bug? Or it's an error of an early step of the installer 
which happens to be used also by the Ubuntu's installer (should they have some 
common parts)?

[Bug 349314] Re: Slow performance and tiling issues on i915

[Vlad Tudorache]

I've just subscribed to this forum. For me, using ASUS EeePC 701 Surf
4G, the solution (also working on Arch and other distros) was VERY
simple. Just add the

OptionTilingFalse

to xorg.conf as shown below (the text between  and  is xorg.conf),
then everything works perfect, no kernel change needed.



# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration
# tool, using values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type man xorg.conf at the shell prompt.)

# This file is automatically updated on xserver-xorg package

# Note that some configuration settings that could be done

# server and settings here are ignored.
#
# If you have edited this file but would like it to be automatically
# updated again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
