Hello list,
I installed Qubes 4.01 on a Lenovo P51 with Hybrid i7 Intel + NVidia
Quadro (chipset NV126) GPU.
I installed it with only the NVidia GPU activated (in BIOS) and it went
well, using the nouveau driver.
At first everything was OK, but as soon as I activate a Windows 7 VM
(whether or not it has the Qubes Windows tools installed) I start
getting display corruption on all desktops even those on which the
Windows VM is not displayed.
The screen goes all black or shows the screensaver prompt at random and
frequent times... Moving the mouse or shifting desktops cause the
windows to redraw and reappear... Annoying.
Corruption stops immediately when stopping the Windows VM.
NOUVEAU
======
So my 1st question is : Does anyone know about a nouveau parameter or
setting that could fix these display corruption issues ?
INSTALLING THE NVIDIA PROPRIETARY DRIVERS
==============================
I tried to install the NVidia Video drivers in dom0, but to no avail.
The Qubes documentation about the NVidia drivers discusses a very old
version and well... It doesnt' work. The RPMfusion NVidia RPMs don't
install, complaining about missing NVIdia libs dependancies (?)...
And I tried to install the binary driver installer from NVidia, but I
could find no way to get the kernel module to compile. (Even though I
installed the proper kernel source headers and utilities).
So my 2nd question is : does anyone have a pointer to a working solution
for installing the NVidia proprietary drivers on Qubes 4.01 with an
up-to-date dom0 ?
INTEL
====
So I decided to check if the Intel GPU would give me better results. I
shifted the BIOS to "hybrid GPU" (there is no “Intel only” setting) and
then I get the following :
The machine boots and shows the 2 Xen loading lines on top of the Lenovo
logo screen, then nothing more happens.
I thought that the machine might be booting up anyway, so after a few
seconds I tried to type my HD passphrase blindly... And then it works !
The machine keeps on booting silently (only SSD activity LED shows that
something is actually happening) then eventually X starts and I get a
proper login screen.
From there on everything seems OK - and I haven't experienced any
display corruption so far, BUT I wonder if there is some setting I could
try to avoid this “blind boot” and get a proper Plymouth boot screen
with a password prompt ?
BTW I do get a proper Plymouth display whent powering the machine down...
Any help highly appreciated.
Kind regards.
