jerky green video output with mplayer and xv

After an upgrade to Ubuntu Jaunty, my mplayer video output (using -vo xv) was completely green and jerky. It turned out that during the upgrade apparently the proprietary nvidia driver was disabled. You simply need to reenable it at System -> Administration -> Hardware Drivers and reboot to fix the problem.

ssh connect error

error:
buffer_get_ret: trying to get more bytes 4 than in buffer 0
buffer_get_int: buffer error

Seems to have something to do with the public key.
It helps to remove ~/.ssh/id_dsa* (or the whole ~/.ssh directory if you want to be sure).

This appeared to me only after the upgrade to Ubuntu Jaunty, I don't know if it's related or what the correct fix is.

There seems to be a matching bug report here.

Update: Apparently it's fixed by now.

Stuttering sound after upgrade to Ubuntu 9.04 (Jaunty)

It turns out that some sound drivers don't work well with PulseAudio, especially regarding the "glitch-free mode". The fix (as described here) is to disable glitch-free:

/etc/pulse/default.pa:

load-module module-hal-detect tsched=0

Afterwards, restart PulseAudio (or simply reboot).

colorgcc from within SCons error: uninitialized value

Eror: Use of uninitialized value $ENV{"HOME"} in concatenation (.) or string at /usr/local/bin/g++ line 211.

Solution, see here:

Replace

$configFile = $ENV{"HOME"} . "/.colorgccrc";

with

my($found_HOME) = 0;
while (my ($key, $value) = each (%ENV))
{
if ($key =~ /HOME/)
{
$found_HOME = 1;
last;
}
}

if ($found_HOME == 0)
{
$ENV{"HOME"} = "/";
}
$configFile = $ENV{"HOME"} . "/.colorgccrc";
