Update on Debian with Lenovo X1 Carbon

On my previous post, I noted that the X11 trackpad customisations. Since then I have implemented the SSD optimisation recommendations as recommended here . I'll give a summary below, where detailed notes on my configuration are here . Firstly are /etc/fstab options to reduce writes: # /dev/sda1 UUID=??? / ext4 discard,noatime,commit=600,errors=remount-ro 0 1 # /dev/sda5 (swap) UUID=??? swap swap sw,discard 0 0 Next, reduce swappiness. Add to /etc/sysctl.conf # optimise for SSD vm.swappiness = 0 Finally, use the deadline scheduler. In /etc/udev/rules.d/60-ssd-scheduler.rules # Only sda is SSD, see https://wiki.debian.org/SSDOptimization # set deadline scheduler for non-rotating disks ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="deadline" In my case I need only do this on the sda device. Please read my document on this as it provides extra informat...

Debian Linux on Lenovo X1 Carbon

I am now using a  Lenovo X1 Carbon  for work. After the installation hassles with the Samsung Series 9 , I'm certainly sticking with Lenovo . It was such a breeze. While I had every intention to maintain the Windows 7 partition, between Lenovo and Windows they consumed all the spare volumes. If required, I can resort to Mac OS X as a commercial alternative. Besides, I have been Windows free since 1998, so have not got a valid reason to retain it. So Windows and Lenovo recovery got dumped onto an unused external hard disk. Someday, I may need to recover, but history is against it. My notes on the installation, though thin are here . It is running Debian , with Xfce installation . The only customisation worth noting are the X11 settings for the trackpad. The custom settings used are: # # File: /usr/share/X11/xorg.conf.d/50-synaptics.conf # Section "InputClass" Identifier "lenovo x1 carbon touchpad" Driver ...

Update on Samsung Series 9

I have been using a Samsung Series 9 with Linux Mint Debian Edition for nearly two years. It is a wonderful machine to use. Crisp screen. Fast. Silent. Lovely keyboard. But it was a real pain to get working reliably under Linux. And with the reported BIOS bug you feel like on tender hooks doing a reinstall or upgrade. I'm, however, relatively happy to report that apart from the occasional kernel panic when using USB ports it has been reliable. Now that I know it is USB sensitive, I take extra precautions when yanking out USB devices. Ensure it is properly unmounted, eject if able. Put machine into suspend mode, then yank out. A pain, but I'm more confident going the extra effort to avoid uncontrolled panics while in the middle of an edit. I am disappointed with recent change of direction of Linux Mint Debian Edition. I like the rolling release. Having successfully implement two updates now, the process is relatively smooth. However they have abandoned the Xfce desktop as...
