Ubuntu updating bios
As usual, I will bring together all the information I have gathered to fix the remaining issue and make the Dell XPS 13 the most enjoyable Ubuntu experience possible.
I will describe how to do a fresh Ubuntu 15.10 installation.
I have not tested the upgrade (15.04 - 15.10), but I see no reason to meet problems doing so. 🙂 In other news, after reading all the great feedback (open source drivers, better ranges, etc…) I have ordered an Intel 7265 wireless card .
As soon as I got it installed, I will review it and write a small guide on how to install it. Back on topic : Install Ubuntu 15.10 on the Dell XPS 13 9343 (2015) : A complete guide ! The current last version, A09, can be downloaded on Dell website.
To locate other BIOS versions you can try and find the version download by navigating through the links located at Caution: If Bit Locker is not suspended before updating the BIOS, the next time you reboot the system it will not recognize the Bit Locker key.
You will then be prompted to enter the recovery key to progress and the system will ask for this on each reboot.
You should be able to spot your mount command in there.Update 28/11/2015 : A tool to disable automatic screen contrast as been uploaded on Github for users affected by the screen contrast issue (see here to test if this affect you).Since I never noticed this issue by myself, I have not tested this tool, but feedback are, as always, welcome 😉 Several users confirmed the tool works fine on 9343 & 9350 models.If the recovery key is not known this can result in data loss or an unnecessary operating system re-install.
