Fixing Recordmydesktop on Ubuntu

Recordmydesktop is broken in Ubuntu 8.04 Hardy Heron due to library changes.
When recordmydesktop is started from command line it shows different errors.

Video related problem:

"This issue is fixed starting from Ubuntu 8.10 (Intrepid Ibex)!

Locking assertion failure.  Backtrace:
#0 /usr/lib/libxcb-xlib.so.0 [[0xb79db767]]
#1 /usr/lib/libxcb-xlib.so.0(xcb_xlib_unlock+0x31) [[0xb79db8b1]]
#2 /usr/lib/libX11.so.6 [[0xb7e34421]]

After while it cannot be finished with Ctrl+C (which alias to kill -s INT PID.)

Audio/sound related problem:

Broken pipe: Underrun occurred.
Broken pipe: Underrun occurred.
Broken pipe: Underrun occurred.

This problem disappears, if sound is not recorded using no-sound switch.

Video error workaround

Workaround to solve this is downgrading libx11-6 package.
Do following steps:

  1. As root user first check package update status, command should return following:

    # dpkg --get-selections | grep libx11-6
    libx11-6                                        install
  2. configure apt, to hold package version:

    # echo "libx11-6 hold" | dpkg --set-selections
  3. Can check again:

    # dpkg --get-selections | grep libx11-6
    libx11-6                                        hold
  4. Download previous package version from http://packages.ubuntu.com/hardy/libs/libx11-6 choose i386 OR amd64
  5. Install previous version:

    # dpkg -i libx11-6_1.1.1-1ubuntu4_i386.deb


    # dpkg -i libx11-6_1.1.1-1ubuntu4_amd64.deb

    according to the OS version.

  6. Check that apt is working correctly:

    # apt-get update
    # apt-get upgrade
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    The following packages have been kept back:
    0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

Sound error workaround

  1. Check, that Intel sound card is used. Following command should return  like this:

    # lsmod|grep snd_hda_intel
    snd_hda_intel         440408  5
    snd_pcm                92168  3 snd_hda_intel,snd_pcm_oss
    snd_page_alloc         13200  2 snd_hda_intel,snd_pcm
    snd_hwdep              12552  1 snd_hda_intel
    snd                    70856  20 snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_hwdep,snd_seq_dummy,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device
  2. Open file /etc/modprobe.d/alsa-base.conf and add following line:

    options snd-hda-intel position_fix=1

    what worked for desktop with ASUS motherboard and Dell Studio 17 laptop, or

    options snd-hda-intel index=0 probe_mask=3 position_fix=3 model=laptop

    what worked on HP Compaq 6510b laptop. See more options in links.

  3. Reboot computer, to be sure libraries are loaded, and check.
