Lenovo P1 Gen 3 issues

General Discussion
1

Can any kind souls help? Been using 4.2.x (most recently .3) on a 32MB Lenovo T450 for ages, and loved it. Bought a bigger spec laptop to run more Qubes, a P1 Gen 3 - i9/64GB which I thought would run 4.3 beautifully.

First problem: it’s a 4K screen, so everything is tiny I managed to fix most of this with XFCE window scaling = 2 and a High DPI theme. Qubes Manager etc. still very small - how do I scale these?

Second problem: 4.3 runs like molasses on this system. So I thought I’d go back to 4.2.4. However, although I can get the installation screen up (providing I edit the GRUB line to include nomodeset acpi=off) I end up on the language selection page of the install with no mouse or keyboard?

Anybody have any thoughts as to how I should proceed? Many thanks…

Hi johnhwoods :slight_smile:

My notes for my 4k screen is:

Make GRUB readable

sudo -i
mkdir /boot/grub2/fonts
cp /usr/share/grub/unicode.pf2 /boot/grub2/fonts
qubes-dom0-update install grub2-efi-x64-modules
sed -i 's/GRUB_TERMINAL_OUTPUT="console"/GRUB_TERMINAL_OUTPUT="gfxterm"/' /etc/default/grub
echo "GRUB_GFXMODE=640x480" >> /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cf

Make the login prompt readable

$ cat /etc/X11/xorg.conf.d/10-screen.conf 
Section "Monitor"
	Identifier "eDP"
	Modeline "1920x1200_60.0"  595.20  1920 3888 3920 4000  1200 2403 2409 2480 -hsync -vsync 
	Option "PreferredMode" "1920x1200_60.0"
EndSection
$
