Scrollback / Terminal History in screen or byobu

This is another case of “should have read the manual”, but there are ways to see previous output in both screen and byobu.

In screen: ctrl + a + [
In byobu: F7

These key combinations cause screen/byobu to enter copy mode, where you can navigate using vi keys, can set marks for copying using return and the like.

This should have been blindingly obvious, but I guess years ago I got used to using screen without scrollback. There more you know… the more it seems that you don’t know anything at all.

My Phone Won’t Load SMS Conversations

I posted this on Google+, but I’m not sure it’s quite the right venue for troubleshoorint queries.

I have an #android #troubleshooting query. I have an HTC Desire HD through 3 in the UK. When I go to open messages using the stock message application, it gives a “loading” spinner but never shows the messages. Inbox and notifications of new messages work fine, but I can’t load conversations. Example attached.

I found a thread from January with what appears to be the same issue, but the suggested solution is “wipe and re-import your messages”, which I’d prefer not to do (http://www.htcdesirehdforum.com/htc-desire-hd-troubleshooting/text-messages-won%27t-load/).

Any thoughts?

Plex Media Server Warning ‘Not Found’ Errors (Fixed)

The media browser on my LG TV has been acting up recently. Instead of listing the categories set up in Plex it pops up a dialog saying “Warning: Not Found”. It does this despite being able to see the Plex Media Server (going to ‘bowse sources’ or similar brings up the server’s name but selecting it gives the same error).

Fortunately Dunhillsmoker on the Plex forums had a solution:

  1. Stop plex service – sudo service plexmediaserver stop
  2. In Plex Plugins directory remove System and Framework bundle directories:
    • mv /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/System.bundle/ ~/plex
    • mv /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/Framework.bundle/ ~/plex
    • (note, depending on permissions you may need ot be root to do this)

    • Start plex service again: sudo service plexmediaserver start
    • This sorted the problem for me.

Adding Workspaces / Virtual Desktops in Cinnamon

Mousing to the “hot corner” in Cinnamon gives an overview of current workspaces, à la expose. Unfortunately a careless click can close one of those workspaces, as I found out last night. Equally, you may feel that the default 2 workspaces is too few and wish to expand upon that. Now, I think the numvber of workspaces should increase automatically*, but it’s nice to control such things. Unfortunately there is no “control panel” option to control the number of virtual desktops, and right clicking the workspace changer widget in the toolbar doesn’t seem to have any useful effect.

However, hit Ctrl+Alt+Down and there should be a ‘+’ icon on the right hand side which will add as many workspaces as you require.

Update: Apparently the hot-corner expose has the plus to add workspaces too. I guess I just didn’t see it there! Cheers James.
