[SOLVED] Xorg segfaulting on ThinkPad T480 with Intel i5-8250U no GPU
I bought a used computer on Ebay last week and have been trying to install Arch Linux (my usual OS). For the most part it went smoothly, it boots fine without any issues and I can get a TTY for my user.
The last step remaining was launching i3wm. However, startx isn't working.
I looked at the Xorg.0.log file and there appears to be a segfault:

EndSectionI tried booting a Linux Mint live USB and everything works fine. I can launch the desktop environment, watch videos etc. without any issues. It also came pre-installed with Windows and Windows worked fine as well. Since I bought the PC second hand I ran all the bios diagnostics (for unrelated reasons) just to check that it's all okay and all tests passed as well. I also tried switching to linux-lts and that made no difference either 
I've spent quite some time looking into this issue and haven't been able to figure it out. So wizards of Arch Linux, do you have any suggestions? Any help is really appreciated

Check the filesystem integrity and drive health.

Re: [SOLVED] Xorg segfaulting on ThinkPad T480 with Intel i5-8250U no GPU
Thanks for the suggestion @Head_on_a_Stick, I booted into the Linux Mint live USB I have, opened the encrypted drive with:
sudo cryptsetup open /dev/nvme0n1p2 rootThen I ran fsck on it:
mint@mint:~$ sudo fsck -f /dev/mapper/root
fsck from util-linux 2.34
e2fsck 1.45.5 (07-Jan-2020)

Pass 5: Checking group summary information
/dev/mapper/root: 423320/31227904 files (0.2% non-contiguous), 7367552/124891473 blocksAfter that, I ran smartctl on the drive and again everything seems to be fine:
mint@mint:~$ sudo smartctl -a /dev/nvme0n1

I don't expect it to be hardware related because I have installed many packages, I've ran some phoronix-test-suite commands to stress test the system, and everything seemed fine when running on Windows which was installed on the drive.
Although, I did get a "blue screen of death" on Windows but I think that was because it was installing some new drivers and something went wrong. I didn't get a chance to check the error messages before the screen closed though. Also I tried compiling a couple of packages and they didn't compile (Ruby 2.7 and pmount) but I think again, that's unlikely to be anything hardware related more likely just some quirks with what I was trying to install (Ruby 3.0 installed fine later).

Re: [SOLVED] Xorg segfaulting on ThinkPad T480 with Intel i5-8250U no GPU
UPDATE: After reinstalling Arch from scratch, X seems to be working fine. I haven't ran any of my setup scripts yet (they install packages I use, configure things etc.), so there is likely something wrong there that broke it. I'm going to start manually running parts of that script until I figure out what part broke my X, and once I do I'll post an update here and mark the thread as solved

Re: [SOLVED] Xorg segfaulting on ThinkPad T480 with Intel i5-8250U no GPU
I tried reintalling Arch Linux and it installed fine and Xorg would launch seemingly without any issues. But after playing around for a bit I noticed many programs would segfault for no apparent reason. Some stuff failed to compile outside of Xorg as well.
This made me suspect it might be hardware related. After asking a question on SuperUser I was advised to run Memtest86. I ran the program and it complained about too many errors.
So it seems in this case, the issue was caused by an issue with the physical RAM sticks, not anything to do with software.
