China Doll: Dell + Ubuntu, Again

Filed under
Ubuntu

It took me a few days to get it right. Didn’t have any problem installing Ubuntu5.10 on my old DIY desktop pc. But the same couldn’t be said about installing the newer release on my brand new Dell. There were unpleasant surprises and frustrating moments:

Getting the Ubuntu6.06 LiveCD to run was easy – it probably didn’t load any exotic video driver even when it was not actually running in Safe Graphic mode. Installing it on my harddisk was entirely a different matter.

As mentioned in my last post, the first surprise was that the Ubuntu6.06 LiveCD just installed its Grub bootloader on the MBR – no warning and no option to choose from. Grub is a fine bootloader but there are two major problems: first, if the computer is a Dell with a special MBR to cater for its two hidden partitions, Grub will simply mess up your specially partitioned harddisk. Second, Grub will invariably see your harddisk arrangement differently than your OS does (whether it’s Ubuntu or Suse) if you are using SATA or USB external harddrive. For my Dell, my internal SATA drive was sde during installation but becomes sda once Ubuntu was booted up (unless you are aware of this, you won’t be able to boot up Ubuntu using the Grub menu. One simple but sure-work way is to press ‘e’ and manually changes the root. In my Dell, I have a card reader which alone takes up sdb, sdc, sdd and sde. So my external drive can be anything from sda to sdg depending on (1) which harddisk I boot up from and (2) whether the OS will first see my card reader or the USB harddisk). One thing for certain is that whichever partition Grub thinks your root actually resides on will be wrong. It is necessary to manually edit the grub menu before Ubuntu will boot up.

  • Madrid GNOME+Rust Hackfest, part 2
    Yesterday we went to the Madrid Rust Meetup, a regular meeting of rustaceans here. Martin talked about WebRender; I talked about refactoring C to port it to Rust, and then Alex talked about Rust's plans for 2018. Fun times.
  • DataworksSummit Berlin - Wednesday morning
    Data strategy - cloud strategy - business strategy: Aligning the three was one of the main themes (initially put forward in his opening keynote by CTO of Hortonworks Scott Gnau) thoughout this weeks Dataworks Summit Berlin kindly organised and hosted by Hortonworks. The event was attended by over 1000 attendees joining from 51 countries. The inspiration hat was put forward in the first keynote by Scott was to take a closer look at the data lifecycle - including the fact that a lot of data is being created (and made available) outside the control of those using it: Smart farming users are using a combination of weather data, information on soil conditions gathered through sensors out in the field in order to inform daily decisions. Manufacturing is moving towards closer monitoring of production lines to spot inefficiencies. Cities are starting to deploy systems that allow for better integration of public services. UX is being optimized through extensive automation.

10 Great Linux GTK Themes For 2018

Customization is a big part of the Linux experience, and your desktop theme is no exception. The world of Linux desktop themes is an ever-evolving one, with new ones replacing old favorites all the time.

These themes aren’t ranked in any particular order. That comes down to a matter or preference. Any one of them can add a whole new look to your GTK-based desktop. Read more
