SSH

  • Installed SSH-Tunnel
  • Files recovered from other installation (ssh-tunnel v2.26 + patch):
/usr/local/bin
-rwxr-xr-x 1 root root ssh-agent-refresh_andlinux.sh
-rwxr-xr-x 1 root root ssh-agent-refresh.sh
-rwxr-xr-x 1 root root ssh.pl
-rwxr-xr-x 1 root root ssh-tunnel.pl
  • User beq06659 - configuration file in directory ~/.ssh:
    • id_rsa || id_rsa.pub || authorized_keys || config* || proxy.conf* || clbanner.txt
  • Disabled SSH Key Agent from Gnome Startup Applications

Terminal

Vim

  • Added ~/.bash_completion from [4] (modified to also take alias v=gvim)

VirtualBox

  • See virtual machine configuration log.
  • Installed with apt (original version 3.2.0)
  • VirtualBox is launched as user root (because it seems that only the current user and root can access PulseAudio in a same X session — see [5])
  • Allow user beq06659 to launch VirtualBox through user root. Add to /etc/sudoers:
beq06659	ALL=NOPASSWD: /usr/bin/VirtualBox
  • Helper script to add to e.g. ~/bin :
#First allow user vbox to connect to X11
#xhost +SI:localuser:vbox
#sudo su vbox -c /usr/bin/VirtualBox&

#New config - run VirtualBox as root to allow sound
sudo /usr/bin/VirtualBox&

Wine

To Do

Hardware

  • Issue — Heavy HW interrupts related to intel graphic card, power saving (sleep), and use of DVI/HDMI interface (module i915, drm, drm_kms_helper).
    • 2.6.32 kernel — udevd eats CPU resource! Launchpad bug 440411, talked on forum 1356215. There was a partial workaround, but it does not work anymore on 2.6.32.28:
    sudo service udevd stop
sudo service udevd start     # After this unfortunately there is no battery state icon anymore (unless reboot, or maybe suspend)
udevadm monitor              # Check that there is no events triggered
    • 2.6.35 kernel (Maverick) — Install a newer version of the kernel, like 2.6.35. But then we have issues with the processes [kslowd001] ... [kslowd004] that hog the cpu even more, and make mouse movements jerky. Launchpad bug 662946, 661012 (dup). See fix in forum 1594239 (Install latest kernel 2.6.37 with partial fix with module drm_kms_helper / i915..., or install kernel 2.6.34). Other links [6]. Workaround:
    echo N > /sys/module/drm_kms_helper/parameters/poll
# OR...
echo "options drm_kms_helper poll=N">/etc/modprobe.d/local.conf   # As root.
    • Some issues seem to be fixed in the latest kernel 2.6.33 for Lucid. See [7] (drm/i915: Disable FBC on 915GM and 945GM...)
    • Workarounds to investigate
      • Install kernel 2.6.34 as suggested at [8]
      • Install latest kernel 2.6.33 for Lucid from Ubuntu Kernel ([9])
  • Issue — Frequent wireless disconnect.
    • Related to intel 5300 chipset (module iwlagn) and 802.11n networks. See Ubuntu Forums thread.
    • Ongoing — Installed a linux-backports-modules-wireless package (linux-backports-modules-wireless-2.6.37-lucid-generic-pae).
    • See this machine HW info for reference information

VirtualBox

  • Issue — VirtualBox - UE slower gui refresh since update to VirtualBox 3.2.4 (previous version was 3.2.0)
  • Issue — VirtualBox - ksoftirqd/0 taking 10-20% CPU. Possible work-around is to add nohz=off to kernel command line, i.e. in /boot/grub/menu.list) (see [10] and [11])
  • Issue — VirtualBox - BT dongle not reconnecting after suspend. It used to work correctly in the past. Is it due to an update?

Other issues

  • Issue — ssh disconnects after some time, autossh can't reconnect. Even doing a simple ssh does not work anymore. Might be due to broken ssh-agent
    • Disable auto-run of Gnome ssh-agent, enabled back my ssh-agent script
  • Issue — synergy unstable. Sometimes CTRL key does not work anymore in the client...
    • Look for alternatives: Synergy+ (SynergyPlus), or x2x (see Synergy page on wikipedia).
  • Issue — Midnight Commander does not colorize different file types. Check here.
    • SOLVED — Use mc official repository instead. See MC page
  • Issues — Serious interferences from Privoxy:
    • Reject URL like .../advies/... and .../ADV_AUTH.CAB (work-around: disable Privoxy AdBlocking via http://p.p).
    • Interference with Altran Timesheet. ActiveX / ASP.NET controls do not work in (Wine) Internet Explorer 6.
  • Issue — Opera 11 - v11 does not support my autoproxy .pac file anymore.
  • Issue — Evince, error in console EggSMClient-WARNING **: Failed to connect to the session manager.... It seems related to apparmor.
    • SOLVED — To solve it [12]:
    cd /etc/apparmor.d/disable
sudo ln -s /etc/apparmor.d/usr.bin.evince usr.bin.evince
sudo /etc/init.d/apparmor restart
  • Issue — ufw user[6].rules files should be stored in /etc/ufw instead of /lib/ufw so that they can be tracked by etckeeper (filed a bug in launchpad, 728128)
  • Issue — Kernel panic when updating to kernel 2.6.32-29, due to trailing dots in /boot/initrd file (bug submitted on launchpad 728430)

Other To Do's

  • ToDo — Try avahi for ZeroConf name resolution and get rid of /etc/hosts.
  • ToDo — look at Compact Human Theme (see Delicious)
  • ToDo — look at Legacy font hinting engine (see Delicious)
  • ToDo — Try to make Nautilus more space efficient. Look at Idea #23573. Try Thunar or PCManFM, or Xfe (the latter does not use gtk theme)
  • ToDo — Also for Eclipse:
  • ToDo — Adapt the search path in /etc/resolv.conf depending on the current network (for now, we statically append be-leu01.nxp.com, when actually this should be done only when on NXP network).
  • ToDo — Pieces of software to try:
  • ToDo — Have a look at Brain Fuck Scheduler, a new kernel scheduler with much better latency for desktops (see [14])
  • ToDo — Install openvpn (+CA Cert authentication?), instead of relying on ssh-tunnel
  • ToDo — Install remote secure storage using encfs over sshf (so that only encrypted data is seen from the server).
  • ToDo— Try Dovecot instead of Courier IMAP? (Dovecot is apparently faster thanks to its index caching feature)
  • ToDo— Setup correct UFW rules for NFS (see [15])
  • ToDo— Look at [[16]] utility for ways to optimize PC power consumption. See also [on LessWatts.org].
