Every now and the touchpad on my T520 either gets stuck in scroll mode, or just stops responding. As a quickfix (not a solution) one can restart the track pad driver with the following two commands:
modprobe -r psmouse
modprobe psmouse proto=imps
Edit:
So, I’ve discovered there is Function key ([Fn]+[F8]) that enables/disables the trackpad, which also works well to solve this issue.
After about three weeks of on-and-off tinkering I finally figured out how to get my HP LaserJet p1102w printer working over wifi. There are tons of forum and blog posts of varried age, discussing this topic. Some say to use “foo2zjs”, I found these to be unhelpful. Others advised using HPLIP, which is available in the Debian repositories, I found these to be very helpful.
sudo aptitude install hplipsudo hp-setup -i
*: I had significant trouble installing the proprietary HP plug-in through the GUI, which is where the majority of my issues came from. I really don’t know why, but everything worked fine once I ran it in verbose mode using “-i”
Other Notes:
Cleanly installing on Debian Sid (or Wheezy)
If you wish to install the client on a Debian system without polluting it with Ubuntu packages and/or other external dependencies, here’s a quick HOWTO.
1. Make sure your apt-get understands multiarch if you’re on amd64
2. Install i386 packages that are available in Debian
apt-get install libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 libcurl3-gnutls:i386 libogg0:i386 libpixman-1-0:i386 libsdl1.2debian:i386 libtheora0:i386 libvorbis0a:i386 libvorbisenc2:i386 libvorbisfile3:i386 libasound2:i386 libc6:i386 libcairo2:i386 libcups2:i386 libdbus-1-3:i386 libfontconfig1:i386 libfreetype6:i386 libgcc1:i386 libgcrypt11:i386 libgdk-pixbuf2.0-0:i386 libglib2.0-0:i386 libgtk2.0-0:i386 libnspr4:i386 libnss3:i386 libopenal1:i386 libpango1.0-0:i386 libpng12-0:i386 libpulse0:i386 libstdc++6:i386 libx11-6:i386 libxext6:i386 libxfixes3:i386 libxi6:i386 libxrandr2:i386 libxrender1:i386 zlib1g:i386
If you are using an NVidia card with the proprietary drivers (I didn’t need this):
apt-get install libgl1-nvidia-glx:i386
3. Choose a directory for Steam, such as /opt/steam
mkdir /opt/steam
cd /opt/steam
4. Download Steam and Ubuntu packages
wget http://media.steampowered.com/client/installer/steam.deb
M=http://ubuntu.wikimedia.org/ubuntu/pool
wget "${M}/main/libj/libjpeg-turbo/libjpeg-turbo8_1.2.1-0ubuntu2_i386.deb"
wget "${M}/main/e/eglibc/libc6_2.15-0ubuntu20_i386.deb"
wget "${M}/universe/j/jockey/jockey-common_0.9.7-0ubuntu11_all.deb"
5. Extract everything in /opt/steam
dpkg -x libjpeg-turbo8_1.2.1-0ubuntu2_i386.deb /opt/steam
dpkg -x libc6_2.15-0ubuntu20_i386.deb /opt/steam
dpkg -x jockey-common_0.9.7-0ubuntu11_all.deb /opt/steam
dpkg -x steam.deb /opt/steam
6. Fix the steam script so that it understands $STEAMLIBS
sed -i 's@/usr/lib@$STEAMLIBS@' /opt/steam/usr/bin/steam
7. Create a custom launch script with the following contents and put it anywhere:
#!/bin/sh
BASE="/opt/steam"
export STEAMLIBS="${BASE}/usr/lib"
export LD_LIBRARY_PATH="${BASE}/lib/i386-linux-gnu:${BASE}/usr/lib/i386-linux-gnu"
export LC_ALL="C"
exec "${BASE}/usr/bin/steam" "$@"
Use chmod ugo+x filename.sh to make the script executable
8. Run
9. Fixing the cursor theme
Steam overwrites the X11 Cursor theme when it launches. This is a problem with Gnome and other WMs/DMs that do not set a cursor theme. You can overcome this for Gnome by setting a mouse cursor theme.
To fix this issue, become root and put the following into /usr/share/icons/default/index.theme (creating the directory /usr/share/icons/default if necessary):
[Icon Theme]Note: Instead of “Adwaita”, you can choose another cursor theme (e.g. Human).
Inherits=Adwaita
Alternatively, you can create a symlink ~/.icons/default that points to the entry for your cursor in /usr/share/icons, for example:
mkdir -p ~/.icons
ln -sT /usr/share/icons/Neutral_Plus ~/.icons/default
If the cursor gets stuck pointing in the wrong direction after exiting Steam, a workaround is to run
xsetroot -cursor_name left_ptr

This works in Debian Wheezy to reverse the scroll direction (aka Natural Scrolling):
echo "pointer = 1 2 3 5 4 7 6 8 9 10 11 12" > ~/.Xmodmap && xmodmap ~/.Xmodmap
No reboot required. Reverting is as easy as running the command above again, but swapping the 5 with the 4 and the 7 with the 6.
