Hi Dinki (curious-mitchell)
I think the point is that this laptop IS supplied AND certified for Ubuntu single boot and as so is supplied in BIOS (they say Legacy) mode.
The LCD back-light issue appeared as a regression for the ones who stayed in BIOS mode, but also appeared for those who switched to UEFI in the aim of double boot with win8. I can't say which ones was the first to meet the problem. **Maybe** using an elder Win compatible with BIOS **could** be a workaround.
The Intel features furbished with UEFI are not supported in Linux, and Mr Linus himself explained why he thinks EFI "sucks"

Maybe this all could help you understanding why we have this "such an ongoing issue"
More: searching about the issue, I found here on launchpad that there are 2 different machines about which the issue is reported: the Dell l322x and the former l321x, both called xps13, what maybe has added confusion.
For me, I bought this l322x certified with Ubuntu because I was fed up with old laptops still having various issues with some piece of hardware in Linux, and at the same time I decided to forgive Windows. Although I am quite newby in Linux and forgiving Windows is another issue for me, I ***decided*** this is my price for the price.
Whatever I must admit that even once this huge step is walked, small issues remain in my l322x, such as hibernation/thaw hanging sometimes, always-on blue-tooth on reboot, a small keyboard back-light miss-behaviour and a touch-pad that I can't set as I want, but maybe this is because I decided to jump into Raring (for which I knew the laptop **was not certified** although it was claimed that all sputnik stuff was embedded) at the same time I reinstalled the OS to remove the bunch of MS-DOS partitions upon which the supplied 12.04 was supplied (now a single / and swap are enough, and even this last is for hibernation only).
To end in an honest remark, I never had real issues while installing Services Pack onto either clients and servers machines from WinNT4 to Win7, and I must admit that the rhythm and depth of changes in Ubuntu remains frightening to me.
Have a good day
