Back in early September, Ubuntu announced that the nightly builds of Ubuntu now supported their new Mir display server, the planned replacement for X.org.
So I tried it. My impressions from that time were:
<<
As of last night - very late last night - I have Ubuntu "Saucy Salamander" up & running with the Mir display server. I am really quite excited about this. Glitches everywhere, but it works!
It's what would have been beta 1 if they still did things like alpha & beta releases, which they don't, because the SABDFL knows all and we must trust in his wisdom. Or something.
Also, I was very amused to read its kernel startup messages.
The kernel version is "Linux 3.11 for Workgroups", & it says:
MODSIGN: Loaded cert 'Magrathea: Glacier signing key XXXXX'
... during boot. :-)

Soon after, I was horrified to discover
the vconsole bug.
But it's getting there.
A fortnight later, ish, I've had another look at the alpha.
It's improved, significantly. They've fixed the security issue - stuff typed in a vconsole no longer appears in the foreground XMir app.
There is still a fair bit of screen flickering, but substantially less. From a quick play, I'd go so far as to say it's usable now; it's gone from horrible to merely distracting. It's the sort of thing I probably lived with in the era of OS/2 2 and Windows 3. :¬)
It's not there yet, not ready for prime-time, but then, they have about a month to go. I'd say it was approaching beta-ready.
