I've been a linux user for the past 5 years.So I don't shy from the cli and troubleshooting issue. It's been a week and when I had tested out a lot of permutation and combinations of what could work and it didn't pan out, so I thought of posting it online, for help.
General Laptop Spec
am was on a dual boot ( windows 8.1 + ubuntu 20.04 ) laptop HP ab032tx, with NVIDIA 940mx graphics card, with propriety drivers, nvidia 450.
Earlier I had open source drivers ( not sure about this though ).
I've been running ubuntu 20.04 from the very start of it's launch in April 2020. There weren't any issue till a week back.
One fine day I suspended my laptop and the next time I open it I see some error regarding
DMAR: [Firmware Bug]: No firmware reserved region can cover this, contact BIOS vendor for fixes ~~~~ Some other content here ~~~~ [drm:fw_domains_get [i915]] *ERROR * render: timed out waiting forcewake ack to clear
The initial suggestion I found was to use
nouveau.modeset=0 through editing the GRUB menu. It did log me in to the system but only once.
I checked a lot of sources :
- Arch IOMMU solved - arch forums
- DMAR Firmware Bug
- Firmware Bug / BIOS is Broken
- Update your kernel - SO
- Fedora - install lm_sensor - Solved - Reddit
- BIOS update should work fine.
- Change the kernel version
- NVIDIA drivers are the culprit.
I acted on both of these one-by-one in the last one week.
- Updated the bios to latest using HP Assistant Didn't help.
Upgrade the kernel
- Logged into recovery mode and did a kernel upgrade, actually added a new update kernel, using ukupgrade
- Didn't help much.
I could log in using the older kernel ( I think it was 5.2.xx or sth ) but that too intermittently, like 1 in 3 times.
NVIDIA drivers are the culprit
Earlier I could install ubuntu , so I installed a fresh copy of ubuntu 20.04 and then installed propriety drivers of NVIDIA i.e. nvidia 450. After reboot it started getting stuck again.
Changing OSArch & Manjaro Linux
I tried arch linux first but that got stuck the same place Then tried Manjaro ( although it was built on Arch, I thought maybe more stable ), stuck at the same place.Pop!_OS
Tried 20.04 nvidia version, it got stuck at the same place as other OSes I read that they've an NVIDIA variant, thought this must be stable. Then I thought of installing with an older kernel so downloaded 18.04. It got stuck here :
Would be extremely grateful if anyone could help me troubleshoot this issue. A lot of my work depends on this.
From discussion in comments it seems that the issue is with i915 Intel GPU Drivers. I had tried installing this using Windows and HP assistant but it crashed even there.
Also how would I install it, if I am not able to install the linux OS itself :?
