[Bug 882225] Re: external monitor no longer works

 

I gave up on Kubuntu and on Ubuntu 11.04 quite a while ago.  I'm having
no such problems now with Ubuntu Server 12.04.2 and KDE.    I'm not
testing the latest development release, as you requested, because this
bug is no longer an issue for us.

Notes:

(1) I can now log into Launchpad again, as you can see.  I couldn't for
a long time, which was frustrating.  Thanks for the heads up,
Christopher.  (And congratulations to the Launchpad team for fixing it.
One doesn't miss the water until the well runs dry.)

(2) For workstations I now use Ubuntu server 12.04.2 for original
installs and I install KDE on top of it, afterwards.  The Kubuntu
installation disk just doesn't work for us; it's too rigid.  The Debian-
style non-graphic installer for Ubuntu Server works pretty well, and it
is vitally important for us.  I hope it's not going away; the loss of
the "alternative installation" disks of yore has made me nervous about
the possibility of losing the far-more-powerful Debian-style installer.

(3) I tried 13.04 and finally reverted to 12.04 because it created
problems.  I don't remember what they were, though.  Sorry.  That was
during the time I couldn't contribute any comments to Launchpad, and I
got discouraged about participating.

Title:
  external monitor no longer works

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I updated my system, a Lenovo X220, this morning.  Upon rebooting, the
  external monitor would not work.  It flickers a lot of mainly-green
  gibberish, and it is unusable.  The internal LCD screen in the
  notebook still works, but not when the external monitor is connected.
  The external monitor is a Samsung 1920x1600.  I rebooted the machine
  again, this time selecting Linux 2.6.38-11.  Now the external monitor
  works properly, just as it used to.  Upgrading the Linux from -11 to
  -12 is clearly what broke the system.
