[Bug 1811641] Re: Wodim permissions error: /usr/bin/wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.

2020-01-24 Thread Dane Mutters
Yes, this looks like the same thing.  The root of the problem is that
/usr/bin/wodim is lacking the u+s (where user=root) permission.

Fixing it might just be a matter of changing the permissions of this
file in the .deb package.  However, if upstream expects wodim to be
installed in the home directory, that would complicate things somewhat.

@Chris Guiver Thank-you for taking the time to respond to this bug
report!

I've done some upgrades, since I posted the original report, but after
uninstalling and reinstalling K3B and Wodim, the symptoms are the same
(partial log output, with error, below).  The "chmod +r /usr/bin/wodim"
trick still functions effectively as a workaround.  Please let me know
if you need anything else.

I'm seeing this bug in Linux Mint 19.1 (Ubuntu 18.04 base).  The audio
devices do not appear and disappear in the "Sounds" GUI.  The workaround
I've found is to do this in a terminal:

pulseaudio -k && sleep 5 ; pulseaudio -D

Sometimes this works for hours, and sometimes it works for minutes,
after killing/restarting the PulseAudio daemon, as above.

[Bug 1811641] [NEW] Wodim permissions error: /usr/bin/wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.

2019-01-13 Thread Dane Mutters
Public bug reported:

Tested on Linux Mint 19.1 AMD64 Cinnamon (Ubuntu 18.04 LTS base).

When copying an audio CD (didn't test with other media), this error
causes the writing process to abort before beginning:

/usr/bin/wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK 
limits.
/usr/bin/wodim: Resource temporarily unavailable. Cannot get mmap for 12587008 
Bytes on /dev/zero.

A workaround is to enable the sticky bit on /usr/bin/wodim, like so:
sudo chmod +s /usr/bin/wodim

My user was already in the cdrom group, so permissions should not have been an 
issue:
groups $USER
myuser : myuser adm cdrom sudo dip plugdev lpadmin sambashare

I'm guessing this can be fixed with a simple change in the package
files, assuming the use of the sticky bit is not a security risk.

Below are logs from two audio CD copying attempts.  The first one is
trying to burn a simulation without the workaround, which fails.  The
second one is a simulation with the workaround, which succeeds.  I also
did a real burn and tested the resulting audio CD, but forgot to save
the log file (sorry).  Suffice to say that it worked.

[Bug 1463120] Re: Failure to boot if fstab disk mounts fail

2018-01-24 Thread Dane Mutters
Could fstab default mount options be changed so that, unless otherwise
specified, failed mount attempts would skip that filesystem and keep
booting (logging an error), instead of dropping to an inaccessible
recovery console? This would let the fstab be fixed with minimal hassle
in a headless environment, so long as the broken mount isn't /boot or /.

[Bug 1686157] [NEW] External Displays Turn Off After Only A Few Seconds Of Inactivity

2017-04-25 Thread Dane Mutters
Public bug reported:

OS VERSION
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=17.04
DISTRIB_CODENAME=zesty
DISTRIB_DESCRIPTION="Ubuntu 17.04"

UPOWER VERSION
upower:
  Installed: 0.99.4-4

  Version table:
 *** 0.99.4-4 500
500 http://us.archive.ubuntu.com/ubuntu zesty/main amd64 Packages
100 /var/lib/dpkg/status

EXPECTED BEHAVIOR
Expected displays to stay on while idle, for at least a few minutes (per Power 
Settings).

WHAT HAPPENED INSTEAD (and hardware information)
I just upgraded from a fully-updated Ubuntu 16.10 64-bit Desktop installation 
to 17.04, using the update manager.  In 16.10 and 16.04 LTS, this issue did not 
exist for me.

I'm using a MacBook Pro with Ubuntu installed in a dual-boot
configuration.  I have two attached monitors: one via the mini
DisplayPort and one via HDMI.  I normally keep the laptop lid closed
while working.  Since the upgrade (persisting through several reboots),
whenever I have the notebook lid closed, if I don't touch the keyboard
or mouse for about 5 seconds, both external displays go into power-
saving mode.  When I touch the keyboard/mouse, again, they instantly
come back up (no delay), indicating that the computer had probably not
been suspended.  If I then don't touch the keyboard/mouse for another 5
seconds, they immediately go back into power saving mode.  (Repeat...)

Going into Display Settings and changing "Built-in Display" to on or off
doesn't seem to have any effect.  When I close the lid, it changes
itself back to "OFF"; and when I open the lid, it changes itself back to
"ON".  (This seems like a sensible behavior.)  Notably, the on/off
switch doesn't seem to move unless I exit and re-enter Display Settings.

I found a workaround to this problem on a forum post:
In "/etc/UPower/UPower.conf", change "IgnoreLid=false" to "IgnoreLid=true".

After doing this, the Built-in Display switch stays on whatever I set it
to, regardless of whether the laptop lid is open or closed (which
probably isn't ideal); but more importantly, the external displays no
longer turn off when idle for a few seconds.  They now obey the settings
I explicitly define in Power Settings.

[Bug 1463120] Re: Failure to boot if fstab disk mounts fail

2017-01-13 Thread Dane Mutters
I've tested this with kernel 4.10-rc3 in a local VirtualBox VM (Ubuntu
Server 16.04), with the same fstab error as above, and am able to
confirm most of the symptoms described by the reporter.

When attempting to 'mount -a', it presents the expected "wrong
filesystem type" error, but doesn't render the system unresponsive.
Upon reboot, however, it drops into a maintenance console without
presenting an error about a failed mount attempt.  Consequently, the
server would be unreachable for maintenance via SSH.

'journalctl -xb' provides a log that contains an error about the failed
mount attempt, but doesn't point to it as the reason for dropping into a
maintenance terminal, and it isn't the last thing logged.

After fixing fstab (which requires physical access) and rebooting
('reboot' from the maintenance console), GRUB does still have a
countdown, but it starts around 10 seconds, instead of 3 seconds (~3
seconds is the default for Ubuntu Server).  Otherwise, at this point,
the system is able to boot up automatically, without issue.

After rebooting a second time (from the normal BASH prompt), the GRUB
countdown is back to ~3 seconds, and the system boots normally
(automatically), from there.

Thanks, again, for helping to resolve this bug.

[Bug 1463120] Re: Failure to boot if fstab disk mounts fail

2017-01-13 Thread Dane Mutters
(New kernel is still compiling...)

I just did a test with a fully-patched, newly spun-up Ubuntu Server
14.04 AWS instance, and the behavior seems to be present with kernel
3.13.0-107.  I can't verify all of the symptoms described by the
reporter, because I don't have physical access; but I get "connection
refused" when trying to SSH into it, after making an intentionally-bad
edit to /etc/fstab.

For completeness, this is the bad edit I made:
/home/ubuntu/test.img   /mnt   ext4   defaults   0   0

The file referenced was created with:
dd if=/dev/zero of=/home/ubuntu/test.img bs=1M count=20

When attempting to mount this file from the command-line, it produces a
"wrong filesystem type" error, as expected.
