Debian Jessie on Dell Latitude 6220


I guess I should’ve read my own posts comparing Linux and Windows, before raving on about Windows last time. The updates on Win7 were a nightmare, with me having to boot and reboot every other hour for a day or two until the download floodgate was shut, almost. I don’t think I’m done. I see that sign next to “Shut Down” where I’m being warned of another upcoming update.

Debian 8That aside, I did want to get my Latitude E6220 on Linux. This time, I’ve chosen to go with Debian, and since I couldn’t choose, I went for both Cinnamon and Mate desktops. Mate gives me the creeps just from the look of the Menu. Cinnamon feels more comfy that way. Next step was to get the drivers all sorted. Frankly, that was a bit easier than getting it done on Windows! You could download the drivers from http://support.dell.com but it wasn’t a clean one-time thing.  I noticed two issues on Linux from the get go:

  • WLAN not working
  • Reboots left the computer hanging

Mercifully, the Ethernet worked right away on Linux – which it did not on Windows on first install. I had to download the Ethernet drivers from Dell’s support site via another PC. So Linux scores better here! A short bit of searching brought me to this resource on the reboot issue. I went into the nearest Latitude on that list and it did mention the reboot issue. The solution was simple:

To solve the reboot issue you’ve to pass the kernel reboot=pci. You can achieve this by adding reboot=pci to GRUB_CMDLINE_LINUX="" in /etc/default/grub.

And after updating that file, I ran update-grub and suffered my final hang.

The WLAN issue was a bit less straightforward. Reading through the WiFi wiki, I identified the adaptor as BCM43228. And I’d have saved myself some time if I’d just scrolled to the end of the PCI section. The wl section covered what I needed. Chased that with a now working reboot and ta da, laptop configured. Since Linux is friendly with Windows, grub handles my dual-boot and I seem to have no issues on that front. I guess I might have issues with the clock as I did previously, but thankfully I do have my old post to help me out.
