This latest UKI work for Fedora will lead to better UEFI Secure Boot support, better supporting TPM measurements and confidential computing, and a more robust boot process.

and HOPEFULLY lead to a less jerky-flashy-switchy boot xperience, looks like a Vegas light show at present. switched to systemd-boot, but it’s only a tiny bit better, still switches modes/blanks screen like five times.

yeah, if you don’t have an encrypted drive (which I’m gonna do on a laptop NEVER) on some OEMs this can look semi-seamless.

here’s what it looks like on a laptop:

    1. OEM logo
    1. screen goes blank, backlight off
    1. light on, OEM logo
    1. blank screen
    1. decrypt password
    1. blank screen
    1. loading spinner with OEM logo
    1. gdm/sddm login screen
    1. blank screen
  • 9a. (sddm) loading animation
  • 9b. (sddm) jerk when fractional scaling kicks in
    1. and finally there’s the desktop

with additional mode switching interjected and occasionally the horror that is GRUB inserts a ‘Loading blah blah’ text message; thankfully we’re getting rid of that.

I’m also trying to get the flicker-free boot. switching to systemd-boot improved the jerkyness, but the blank before the decrypt password remains.

I’ve enabled suspend-then-hibernate and whereas earlier I’ve had to endure this jerkyness rarely, now I have to witness it multiple times a day when resuming from disk. at least it’s faster than cold boot.

Shortcomings and regressions in Plasma 6 wayland for artists using and configuring graphic tablets

While cutting edge testing distribution such as Fedora are going Wayland only and the proponents of such move say that this push is required to shake things out. I would like to highlight some of the things which are not there yet on the graphic tablet configuration front on plasma wayland. Although the basic support for the...

dingdongitsabear,

I have no direct experience with any pen related issues but kudos for taking the time to open all them reports. sooner or later, someone is going to tackle those issues. let’s hope it’s soon.

there’s a lot of things that need to be re-implemented in wayland and it currently sucks for a lot of people; but forcing change by pushing wayland onto the users is the only way forward, way too many people are comfortable with status quo.

dingdongitsabear,

I’m not calling you a reactionary, just seen way too many people maintaining “this is fine” for issues that are anything but.

pipewire sucked a lot for the longest time, at least for several setups I know. but it got better and more dependable by getting forced onto users. if it had waited to be 100%, it wouldn’t ever be in production.

this is a “build the plane while flying it” situation, if the stress on the vanguard is not for you, then step back for a while and try again in a couple of months, you have options.

dingdongitsabear,

whatever distro you choose, disable the nvidia graphics first. you’ll lose the display out but you’ll gain a cooler laptop with better autonomy. integrated graphics is more than enough to drive Plasma.

dingdongitsabear,

thanks. unfortunately, didn’t fix my problem.

I also have a T480s with similar hardware to your Dell and it works without issues, no kernel switches necessary.

dingdongitsabear, (edited )

you have faulty hardware, whether it’s RAM or cooling or storage related, no way to tell but crashes like that don’t happen nowadays.

edit: I recall having some issues with a 7490 a few years back, it needed some special module for the fan or the sensors, not sure. don’t know if that’s your issue, but look it up.

dingdongitsabear, (edited )

I think you mistyped the model, if it’s a 7390 it should be the same hardware as the 7490 I’ve mentioned. the module I needed was i8k, check if your model needs it.

dingdongitsabear,

I have an issue involving similar hardware, can you share the mandatory stuff for 8th gen iGPUs? read through the intel_graphics article but found no direct mention.

did you try the i8k module?

dingdongitsabear,

thanks for chiming in. yeah, some surface models are prone to have these issues as well, I remember trying that in windows but with no results. in linux, the i915 driver doesn’t have that option any more, or I suck at reading comprehension… anyhow, not sure that’s the same issue, as my device has these spells also when on AC power but with battery installed. the only times it’s functioning properly is when it’s on AC and with battery removed. but this looks like a promising lead to research further.

this if from a F38 live image.

battery is (or should be) 7.6V 42Wh. BIOS rates condition as excellent, 92% battery health. no visible deformations, as stated.

naturally, during this whole period the screen didn’t flicker once.

dingdongitsabear,

sure, it’s a decade old device worth like $100, if that. of course this is a tinkering exercise. but I’m referring to the fact that it works perfectly without battery, it obviously has some power limiting then (no speedstep, no turbo). so I was looking to recreate that behavior with the battery.

dingdongitsabear,

that seems reasonable but I don’t trust my chubby fingers, everything is so tiny I’m afraid I’ll short something.

dingdongitsabear,

naturally, it began again after waking from sleep. that’s why it’s so darn tiresome diagnosing it, you never know if the tweak you’ve made has any effect, sometimes it works for hours, sometimes it freaks out after seconds.

if the battery is the culprit, shouldn’t it stop being a problem when running the device on external power? it’s not like it’s constantly charging the battery and simultaneously draining it; at least, no laptop I know of does that. and if the display cable is faulty, then it should also have those flickers when running it without battery. that never happens.

dingdongitsabear,

sadly that’s not an option at this point.

dingdongitsabear, (edited )

hmm, there’s an idea. I’ll try to shield the cable from the battery with cardboard and aluminium foil.

edit: nah.

dingdongitsabear,

nah, tried that when I had windows on it. that and a bunch of other stuff from the unhelpfulest site on the webz - dell.com. screen rates and resolutions and auto brightness as well. the battery contacts are way too tiny for me to do anything meaningful there. besides, I’m thinking that if the battery is the problem, then there shouldn’t be any issues when running the thing on external power; it’s not like the battery is powering the laptop when connected to external power, it’s running on external power and using the surplus to charge the battery.

dingdongitsabear,

thanks for the input. so no amount of tweaking and kernel switches and MSRs and what not can be utilized to lower or alter the performance so that it behaves? the repair route isn’t likely unfortunately
