Daniel, I disagree. This bug is actually about the fact that the test crafted in /lib/udev/rules.d/61-gdm.rules doesn't parse as expected in udev. We also should probably file a bug report against upstream udev as the changes added to support escaped quotes in #6890 aren't robust enough. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1969447 Title: 42.0-1ubuntu6 doesn't recongize the presence of NVIDIA_PRESERVE_VIDEO_MEMORY_ALLOCATIONS=1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1969447/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I'm not totally sure we need this bug. The problem with Wayland sessions missing on Nvidia is tracked in bug 1968929. And the use of NVIDIA_PRESERVE_VIDEO_MEMORY_ALLOCATIONS should be tracked in bug 1876632. So essentially this bug is just pointing out that we haven't fixed bug 1876632 yet. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1969447 Title: 42.0-1ubuntu6 doesn't recongize the presence of NVIDIA_PRESERVE_VIDEO_MEMORY_ALLOCATIONS=1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1969447/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Note that I stumbled onto the above fix after noticing the example shown
for the udev escaped quoting support showed an example with double
quotes surrounded by single quotes which in turn surrounded escaped
double quotes...
https://git.alternativebit.fr/NinjaTrappeur/Systemd/commit/7e760b79ad143b26a5c937afa7666a7c40508f85
udev-rules: all values can contain escaped double quotes now (#6890)
This is primarly useful to support escaped double quotes in PROGRAM or
IMPORT{program} directives.
The only possibilty before this patch was to use an external shell script but
this seems too cumbersome for trivial logics such as
PROGRAM=="/bin/sh -c 'FOO=\"%s{model}\"; echo ${FOO:0:4}'"
or any similar shell constructs that needs to deals with patterns including
whitespaces.
As it's the case for single quote and for directives running a program, words
within escaped double quotes will be considered as a single argument.
Fixes: #6835

I have found that current /lib/udev/rules.d/61-gdm.rules can be fixed by
swapping the order of the single and escaped double quotes from...
IMPORT{program}="/bin/sh -c \"sed -e 's/: /=/g' -e
's/\([^[:upper:]]\)\([[:upper:]]\)/\1_\2/g' -e 's/[[:lower:]]/\U&/g' -e
's/^/NVIDIA_/' /proc/driver/nvidia/params\""
which fails to parse correctly to...
IMPORT{program}="/bin/sh -c 'sed -e \"s/: /=/g\" -e
\"s/\([^[:upper:]]\)\([[:upper:]]\)/\1_\2/g\" -e \"s/[[:lower:]]/\U&/g\"
-e \"s/^/NVIDIA_/\" /proc/driver/nvidia/params'"
which parses properly and allows the test for
ENV{NVIDIA_PRESERVE_VIDEO_MEMORY_ALLOCATIONS}!="1",
GOTO="gdm_disable_wayland"
to succeed when /etc/modprobe.d/nvidia-power-management.conf contains...
options nvidia NVreg_PreserveVideoMemoryAllocations=1

I am wondering if the use of escaped quotes in the failing rule of /lib/udev/rules.d/61-gdm.rules is really being honored. There don't seem to be any other examples of deployed udev rules which actually use such escaped quotes. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1969447 Title: 42.0-1ubuntu6 doesn't recongize the presence of NVIDIA_PRESERVE_VIDEO_MEMORY_ALLOCATIONS=1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1969447/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
