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.
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.
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.
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
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.
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.
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.
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.
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.
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.
