Ubuntu Upgrade from Jaunty to KarmicI just updated the ubuntu on my Lenovo 3000 v100, and had to troubleshoot couple things. Here they are:
No sound under gnomeIt seems like the pulse-audio did not do a good job for detecting my audio devices. I tried to install the alsa drivers by: sudo apt-get install linux-backports-modules-alsa-karmic-generic but I still don't have any sound after a reboot. Following the next suggestion I checked what was using the sound device and sure enough slmodemd grabbed it before pulse-audio. $ sudo fuser -v /dev/dsp* /dev/snd/* /dev/seq*
USER PID ACCESS COMMAND
/dev/snd/controlC0: Slmodemd 1177 F.... slmodemd
/dev/snd/pcmC0D6c: Slmodemd 1177 F...m slmodemd
/dev/snd/pcmC0D6p: Slmodemd 1177 F...m slmodemd
$ sudo killall slmodemd
$ sudo killall pulseaudio Now sound is back! Now we have to make sure pulseaudio is loaded before slmodemd. Every once in a while I need to use the modem (for fax etc.) so I would like to keep the modem daemon. I checked the /etc/rc5.d folder to see when each daemon starts and not surprisingly: S12sl-modem-daemon S50pulseaudio so we have to rename the sl-modem-daemon so that it loads after pulse audio. The following command will do just that: sudo mv S12sl-modem-daemon S99sl-modem-daemon See Also:Kile (Pdflatex) problems
Kile does not compile my articles anymore, the error message says: Unknown graphics extension: .eps. ...includegraphics[width=4.5in]{./Fig8b.eps}} After a quick check I realized that I was not using pdflatex before. So I had to setup Kile to use Latex again. Open Kile and go to Settings> Configure Kile > Build (from the left column) > Quickbuild (from the middle column) > and select Latex+DVItoPS+PStoPDF+ViewPDF from the top. Missing Colobars in Hamster OverviewI couldn't find a solution to that. But here is a Bug-Report to follow. Bug # 451916 Matlab Figure Problem on Multiple Screens I couldn't find much on this either.
