Certainly if a session type crashes then it will be removed from the
login menu. Please report the crash in a new bug by following
https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

It might be a known issue but which known issue we don't yet know.

[Bug 1968929] Re: Missing Wayland login option on NVIDIA systems

2022-05-03 Thread Ralph Schmieder
funny enough, I have the opposite issue, 22.04 w/ gdm3 42.0-1ubuntu7
installed and Nvidia 510 driver.  Hardware is a Dell XPS 15 9510 w/
GeForce RTX 3050 Ti Laptop GPU.

When selecting the Nvidia "On-Demand" profile, I get both, Wayland and
X11 in GDM.  However, when I select "Performance Mode", X11 stops from
working, it's not offered in the gear menu anymore.  What's worse, even
if I disable Wayland in /etc/gdm3/custom.conf, it seems like the X
server simply crashes:

"gdm3" is not usually an Nvidia issue so does not usually require the
involvement of people with Nvidia hardware. This was an unusual case.
But as usual we all worked together and got it solved.

2022-05-02 Thread Daniel van Vugt
Jesse,

It's complicated. There were too many intermediate versions (with
additional important fixes like bug 1969097) in between to roll back
over. The person in charge of that package does not have Nvidia hardware
to test with either. Also this all happened only hours before the
release so we had to move quickly. Rolling back was never really an
option.

Please report a new bug for your "lock ups" if that's a problem.

As for the Night Light issue you mention, please create an additional
new bug about it. It might be specific to Nvidia on Wayland
(https://gitlab.gnome.org/GNOME/mutter/-/issues/290), or it might be
specific to Intel 12th gen chips (bug 1967274), or it might be something
else... I'm not aware of Night Light regressing in any case, unless you
count the change from X11 to Wayland.

P.S. You may also be interested in tracking the list of nvidia-wayland
bugs: https://bugs.launchpad.net/ubuntu/+bugs?field.tag=nvidia-wayland

Night Light was previously working on my hybrid Nvidia laptop before the
recent changes that switched Wayland to X11. I manually switched back to
Wayland, but now Night Light is not working.

Why are the changes that caused these bugs not being rolled back?

[Bug 1968929] Re: Missing Wayland login option on NVIDIA systems

2022-05-02 Thread Jesse Johnson
To clarify, all future installs with hybrid Nvidia graphics will now
default to Wayland? So users won't have to work around this issue by
manually selecting Wayland in the log in screen? Cannot expect the
average user to figure this out.

I am unclear why this bug was not rolled back once it was identified,
and a fix that doesn't require manual intervention later released? Does
the package release system not support rollbacks?

My experience:

Have a hybrid Nvidia laptop. After updating and rebooting, suddenly
sleep caused laptop to lock up into a black screen requiring reboot, so
effectively the laptop could not be used as a laptop. Upgraded to gdm3
42.0-1ubuntu7, which defaulted to X11 after reboot, had to log out and
manually select Wayland which fixed suspend. Wayland selection persisted
between reboots.

Nekaterih paketov ni mogoče namestiti. To lahko pomeni, da ste zahtevali

Naslednji podatki vam bodo morda pomagali rešiti težavo:

Naslednji paketi imajo nerešene odvisnosti:

E: Ni mogoče popraviti težav. Imate pokvarjene pakete.

To translate, it says something about unresolved dependencies
(gir1.2-gdm-1.0 and libgdm1).

[Bug 1968929] Re: Missing Wayland login option on NVIDIA systems

2022-04-23 Thread Marcos Alano
I have a Dell laptop that have an option in BIOS to always use the NVIDIA GPU 
instead of Intel/NVIDIA, and that the option I keep selected.
In the login screen, the gear shows "Ubuntu" and "Ubuntu on Wayland" options, 
so I think it's ok for non-hybrid machines until we fix all the problems.

2022-04-23 Thread Jeremy Bicha
My system doesn't have Nvidia graphics. I upgraded my gdm3 to
42.0-1ubuntu7 , restarted my computer and verified that my default
session is still Ubuntu and there is an Ubuntu on Xorg login option.
This verifies Test Case 2.

I don't think that comment 39 is sufficient to block this bug fix so I'm
removing the verification-failed tag.

I have a laptop with Intel+NVIDIA combo. I did a fresh install. Ubuntu
uses Xorg and now it even feels choppier with more screen tearing than
my previous 20.04 installation. I see none of the speed improvement
claims from 22.04's release notes in the gnome session.

I can confirm that with the proposed update on a previously impacted
system (where Wayland was not available as an option) with an NVIDIA
only GPU (RTX3090), "Test Case 1" behaves after the proposed update as
expected: the Wayland option is made available, but default is "Ubuntu"
(not "Ubuntu on Wayland").

Hello Marcos, or anyone else affected,

Accepted gdm3 into jammy-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/gdm3/42.0-1ubuntu7 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

  Hybrid systems should actually be using the Intel graphics for to run GNOME

  There are some suspend & resume issues, an issue with gsync, etc. which

  I'm using Ubuntu 22.04 on a Dell G15 5511 laptop that have an NVIDIA 3060 
GPU. I saw in the last update in the gdm3 package that Wayland will be disabled 
in machines with hybrid graphics.
  The question is: In this laptop I can enable optimus to use Intel and 
sometimes NVIDIA or keep only on NVIDIA (I use this option). So even it's 
detected two GPUs the Intel one is unused.
  I think the problem could extend for people with a desktop with an integrated 
intel GPU and a discrete NVIDIA GPU, since both will be present in the system.
  So maybe will be necessary to check with more accuracy to check if there are 
two GPUs, but only one is being used or have a documented option to force the 
enablement of Wayland.

I too am affected by this bug.
System: Acer Predator Helios 300 Acer Predator PH315-53
GPU: Intel Integrated/ RTX 3060 Mobile

If I use prime-select intel then the wayland option appears and works fine.
If I use prime-select nvidia or prime-select on-demand then wayland option 
dissappears. I used to use the 22.04 beta few weeks back before nuking it to 
the 22.04 stable release and wayland used to work fine there with on-demand 
option.

One thing to note is that in Hybrid+wayland egl was not working properly
which caused apps like mpv to crash(https://bugs.launchpad.net/egl-
wayland/+bug/1968488). Im not sure if the issue is fixed rn.

I am not certain this is related, but on a fresh install on my laptop
with a gtx 1050 2gb, I installed the nvidia drivers. The 'intel
graphics' option was greyed out on the nvidia prime selection and the
wayland session was not available (gear missing).

I used the terminal command 'sudo prime-select intel'.

After reboot, the intel option is selected as well as greyed out and
wayland is the default and running smoothly (actually there was some lag
on X11, esp on boot with the dock, which is now gone).

I just did a fresh install of the official release of 22.04 LTS image
today, and hit this problem. I see no gear icon, and it defaults to X11,
with no option to select Wayland, whether I have just the NVIDIA GPU
enabled, or both the Intel integrated GPU and the NVIDIA discrete GPU
enabled in hybrid mode.

I had previously installed a nightly build of 22.04 LTS (beta) last
week, and had the gear as an option, and was able to select and use
Wayland.

I updated my 22.04 system today (with Nvidia proprietary drivers and a
3080 card). I added this file:

cat /etc/modprobe.d/nvidia-power-management.conf 
options nvidia NVreg_PreserveVideoMemoryAllocations=1

Now both Wayland and suspend/resume seems to work for the first time
