It took me quite many hours. There are many posts online but at the same time many of them lead to dead ends. As mentioned in this post, the instruction described on help.ubuntu.com allows one to setup custom key but at the same time leaves a big security hole on ssh. Because everyone can ssh to…
I used to use Samba to share folders between my laptop and my desktop. It works fine until 10.10 that Ubuntu decided to act crazy and screw the whole mount.cifs thing. I still managed to share the folders for a while after some tweaks with /etc/fstab. But today it is just not working anymore. I…
Okay. I found this so-called opacify feature extremely annoying (I’ll just call it retarded to show my anger towards it). Basically, it makes any other overlapping windows to fade out from the window currently moused over with. It doesn’t sound so annoying but you will know if you use it for an hour or two….
It has been addressed in many posts such as this. I include this just as a personal note. The random decision by Ubuntu is quite a bit annoying sometimes, even though I still love it…
This guide is great. But one has to install and setup apache and mysql first (if haven’t). I follow this guide and add this line before the earlier guide and then it works perfectly. sudo apt-get install apache2 php5 mysql-server phpmyadmin But be sure to restart apache after installation. sudo /etc/init.d/apache2 restart
Our GPU computer crashed the day before yesterday. Since there are multiple users on that machine, I don’t know who made the mess. Anyway, we simply could no longer start gnome. So we ended up reinstalling everything. This link is helpful. But installation did not work in our case. We had the nasty “low-resolution” problem….
Even though I love Ubuntu, I can see why many people will never switch to Linux at this stage. It took me a while to try to do as simple as changing the time zone of my laptop when I have a short vacation back home in Hong Kong. Some Linux lovers will probably disapprove…
ssh is great. But sometimes I just need a desktop. The remote desktop functionality offered by Ubuntu is kind of limited. For example, I just don’t know how I can enable remote desktop easily in the first place if one is not in front of the host already. Moreover, Ubuntu’s remote desktop is limited to…
I did an extremely stupid thing today. It all started when I tried to fix some conflicting issue of OpenCV and ffmpeg. I installed and reinstalled many times. I tried this on my desktop and eventually tried it also on my laptop. For some reasons, I could not install some required package (libxcb1-dev). It showed…
It was a total pain to try to have skype and ubuntu jaunty work happily together. My miscellaneous problems with mic just can never be resolved. The medibuntu package simply doesn’t work for me. I even go as far to uninstall pulseaudio. Unfortunately, even that doesn’t make my skype work. Mic worked for the first…
