The BIOS graphics options I've seen sometimes allow hybrid, but also include a strict integrated-only option that completely disables the discrete GPU. -- Chris Laprise, tas...@posteo.net https://github.com/tasket https://twitter.com/ttaskett PGP: BEE2 20C5 356E 764A 73EB 4AB3 1DC4 D106 F07F 1886 -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

VS: [qubes-users] KDE Plasma in dom0 under R4.0.3
This is true, I have one of the first P51 models and it used to have threewi options in the BIOS 1) integrated, 2) hybrid and 3) discrete.With integrated mode everything worked like a dream, also the HDMI output.But after I got some serious problems after an year with the internal display (when powered up the display got distorted after few minutes), lenovo service changed the motherboard and after that there was only two options left in the BIOS (hybrid and discrete). Also the HDMI connector does not work anymore :( Lähetetty Jolla Sailfish -älypuhelimestani.Lähettäjä: brendan.h...@gmail.comLähetetty: sunnuntaina 12. huhtikuuta 2020 1.53Päättymisaika: qubes-usersAihe: Re: [qubes-users] KDE Plasma in dom0 under R4.0.3On Saturday, April 11, 2020 at 7:10:18 PM UTC, Sven Semmler wrote:On Sat, Apr 11, 2020 at 02:48:17PM -0400, Chris Laprise wrote: > I've never had a problem with KDE in dom0 as long as the display manager is > switched to sddm and BIOS is set to integrated graphics.

So while I am sure your statement is correct in general, on my particular setup switching to the discrete graphics makes everything work. Every rule has an exception I guess. Hybrid graphics routing for nvidia optimus has changed over the years. On older laptop models, one could select among integrated, hybrid and discrete. For many of us, selecting integrated graphics was the most stable option.On more recent optimus laptops, integrated is no longer an option, you can only select between hybrid and discrete. I believe this limitation is due to how the signal routing now requires some level of firmware support in the discrete chipset to get video out. In any case, hybrid has always (nearly?) impossible to get working under Xen/Qubes...so the next best option has been making discrete work.Brendan -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
