Having shot myself in the foot by rewriting already pushed history, it occurred to me that perhaps I could have the commits list in interactive rebase reflect the commits’ push status in color. If lines of commits that I’ve already pushed to a remote were colored red (or any sufficiently differentiating color), I might actually notice when I’m about to screw up again.

To illustrate what I mean, here’s a mockup I made. This is what it would look like if this was my commit history, and 8b0ce7b was the last commit I had already pushed to a remote:

I have no previous experience in modifying syntax highlighting code, and I have no idea if what I’m suggesting is even possible with vim, so I figured I’d open this request first in case it’s a silly idea, or conversely, if you deem this useful enough to implement yourself.

Currently experiencing this. `lsof /var/lib/dpkg/lock` shows only ”focal” as holding the lock. The same ”focal” process is also eating up all of the CPU. No dpkg or apt processes are listed by `ps` either.

After updating Firefox from 78 to 79, hardware-accelerated video decoding no longer works properly in Wayland: streaming video gets cut off with an error message from the service.

== Steps to reproduce ==
1. Follow the steps in [1] to enable VA-API.
2. Open a Youtube/Twitch video (for instance https://www.twitch.tv/rifftrax), press play

== What I expect to happen ==
For the video be played without issues (as it did with Firefox 78).

== What happens ==
After playing for a while (anything from just a few seconds to a couple of minutes), the video stops and is replaced by a service-specific error message, such as error #3000 (in case of Twitch) or (Youtube). Even when playing, the video also flickers green. After reloading the tab, the video again plays for a few seconds before the error message reappears.

== Other info ==
A fix is apparently already in the works upstream [2].

I can confirm that 3.36.4-1ubuntu1~20.04.1 from -proposed fixed the issue (in Boxes) for me, i.e. the dialog text is now wrapped and hence entirely legible.

A fix has recently been committed upstream: https://salsa.debian.org/debian/ddclient/-/commit/82d99d1dfb0fb002a15e081fdc7ccf8f96215dc6

After doing manual dconf cleanup, I’ve been unable to reproduce the issue. That’s since posting the previous comment, so a few days now. So I think I’ll hold off on reporting this upstream for the time being, but I’ll go ahead and do that if the problem still manifests itself.

Thanks again, Daniel.

I removed all but Desktop Icons, Ubuntu AppIndicators and Ubuntu Dock, rebooted and then reproduced the issue. Luckily I’ve found one way to reproduce this, albeit somewhat convoluted and still a bit unreliable, involving Synaptic and window tiling. And as it doesn’t seem to trigger the issue when using another account, I’m now working through settings differences between the two in hopes of finding something crucial.

While doing so, I did discover that dconf-editor is similarly affected:

Looks like dconf-editor did not exit with FAILURE, but the dconf-editor window did disappear just as Gnome terminal’s did.

Happened again:

But there’s still nothing in /var/crash, nor on the Error Tracker (aside from the aforementioned, unrelated crash from last week).

Turns out the online service was just a little slow to update, and there are in fact reports sent. But the only one post-20.04-upgrade is [1] from last week, which is a gnome-shell crash and IIRC, unrelated to the terminal issue here. It seemed to be triggered by something related to media files and Nautilus, and the logs from the time are different; I’m attaching them here. (I had separated gnome-shell logs out from the main syslog, but I’ve since reverted back to having everything in syslog.)

Thanks for the instructions, Daniel! I found no crash files either locally or online, so I’ve implemented the workaround now, and will try to trigger the crash again.
