Hi, After solving the problem of loading nvidia drivers thanks to the help on this list, especially Andrei, I open a new thread in the hope that maybe, maybe my nvidia card can be used one day. I have an Asus GL552V laptop, i7 6700, optimus graphics intel/nvidia running opensuse leap 42.3, KDE It now runs the intel graphics only, in a terrible way with lot of flickering. I cannot disable the intel graphics or make the nvidia graphics primary in the BIOS (there are no such options there and I double-double-checked...). I would love to be able to switch between both cards (intel/nvidia) just as it was possible on OpenSuse 13x using suse-prime. If that's not possible, I'd love to have nvidia activated all the time. I don't want bumblebee, as for my work-flow it is not really helpful. I have installed the nvidia drivers from the opensuse nvidia repositiory and they are up and loaded. But running prime-select (installed from the 42.3 repo) something breaks so that I cannot logout from the KDE session nor shutdown with the KDE menu button. As somebody suggested I changed the display manager from sddm to kdm, but that didn't help. How can I goon testing and maybe solve the problem? What and where do I have to look? Thanks for your time and energy and help!

may be you could start here, find a suse-prime mailing list or ask the maintainer directly may be it's just a little change that made it break :-( good luck jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The first step is to enable KMS in nvidia-drm. This is documented in nVidia README. You may need to recreate initrd because I think openSUSE adds drivers there (mkinitrd). After rebooting with KMS enabled show lspci -nnk xrandr --listproviders glxinfo | grep vendor as well as Xorg log. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

This enables KMS for current boot. It will be lost after reboot. To enable it permanently you need to create modprobe configuration file. echo options nvidia-drm modeset=1 > /etc/modprobe.d/nvidia-drm.conf mkinitrd reboot

OK, checking your versions it was probably not necessary. It is only required for PRIME synchronization, but it needs Xorg 1.19 anyway.

This is the problem and my great fear... I only have this laptop with me (I am moving around and don't have friends here...) and I /need/ it for work, would be terrible if I could not use it... So I can only try things that will at least allow me to enter in text mode to undo what caused the problem...

Yes, I use this when the graphical login doesn't work. However Andrei's "if anything goes wrong with X configuration, you may not be able to access your system" makes me fear that even this wouldn't work anymore. As long as I can go to text mode with init 3 I guess everything can be reversed (at least with the help of the list ;-) ) .

Not that it could be of any use to Daniel now, but even though I have many computers but none mobile, this is one reason (of several) every PC of mine that I did any OS installation on is multiboot.

This is something I never thought about. I should have done this on my laptop, it sounds very reasonable to me. But well, I haven't. It wasn't so important though.

I almost always create an extra system; it can be a small partition only for testing, like 8 GB. 15 is much better. I didn't on my last install, a small laptop with a small SSD.

Maximum size of my test /s is 10, but the vast majority are less than 7200M, mostly 5600M. When multibooting for the primary purpose of testing a beta that is expected to become a replacement main installation, then size of test / is best identical. That allows the test to become the operational via a rather simple cloning operation followed by distribution upgrade when upgrade rather than fresh is desired, without disturbing the existing normal. My test partitions share a single /home/ and single /usr/local/ partition, are installed with recommends disabled, and have installed only one DE besides the default IceWM, so have modest space requirements.

...

I didn't on my last install, a small laptop with a small SSD. However, there is an alternative on modern laptops: an external hard disk via USB3.

USB is/are a(re) different bus(es), which is/are subject to different device enumeration order and thus different device name assignment. Thus, I never do USB HD boot. I use eSATA when I need to boot from an external HD. That way, the BIOS is able to assist when necessary with the problems variable device names can cause during rescue operations. Mind you because all here are multiboot, external HD boot from either bus is virtually never a necessity. A stick I have used, but only for feeding a BIOS updater's own integrated BIOS update utility its new code.

If you only need it for rescue, the openSUSE rescue image on a stick is enough.-- "Wisdom is supreme; therefore get wisdom. Whatever else you get, get wisdom." Proverbs 4:7 (New Living Translation)

My strategy is a main system, big, home plus root, and a small extra test/rescue system (single partition), 9..15 GB. Once done testing, I upgrade the main system, not switch.

I was referring to people other than Carlos E. R. needing help with or trying to use rescue modes provided through various rescue sources. Real humans can't be expected to work with UUIDs (or have existing filesystem labels). UUIDs are for software like grub, systemd and kernel, not people. -- "Wisdom is supreme; therefore get wisdom.

:-) YaST by default uses UUIDs since years, and so does grub. Usage of device names such as /dev/sda is deprecated and should not be created by any automatic configuration tool used by openSUSE, and if done should be reported as bug. In fact, a name such as /dev/sda in fstab since years makes YaST abort the system upgrade, asking the admin to remove the offending line. There was a post when it happened to someone not 4 months ago. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)

LOL! Lewis Carrol or a computer science purist or student of Alfred Korzybski might argue with that. A Zen Master might also, while his finger is pointing to the moon. Or not. In the mean time, as I said elsewhere, we are[1] human. Well some of us claim to be. Some of the time. We are not 'grub'. We are not YaST. We are not the kernel. In English, the very 'to be' is often problematic because we confuse its use relating to identity with its other uses: https://en.wikipedia.org/wiki/E-Prime#Different_functions_of_%22to_be%22 Kellogg and Bourland describe misuse of the verb to be as creating a "deity mode of speech", allowing "even the most ignorant to transform their opinions magically into god-like pronouncements on the nature of things" [1] That is use of the verb 'to be' as class membership. You might think that its use is one of 'identity', but not in this context. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Well, if you define years by 1+, then maybe that is a true statement, but my 42.2 install did install to */dev/sda* (using /dev/sda in fstab and all GRUB files, not UUID) which resulted in grub overwriting my Win10 boot code when I moved the drive to a second drive bay and put the Win10 disk back in the laptop. I had to manually update all grub and the fstab file to remove the /dev/sda and convert to UUID. -- David C. Rankin, J.D.,P.E.

Yes, I know, but it is a bug. Try to upgrade 13.1 to Leap with /dev/sda something in fstab and it will abort on you. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)

+1 That's why we have DNS. That's why the cities we live in have names and we don't use Latitude/Longitude to describe where we live. Even the few of us who are good at mental arithmetic don't think in those sort of numbers. Whenever I set up a new drive I use some to tool to labels the disk. It may be ROOT4 or HOME17 or PHOTO18, and I try hard to make it both unique and meaningful. Occasionally I find the grub.conf has a UUID and I struggle to translate that and replace it with a meaningful /dev/disk/by-label/ or /dev/disk/by-partlabel/ YMMV but why make life difficult for yourself.

hm. If you use windows or mac in fact you do what the computer says, one of the reasons why I use Linux. Even android wants to give me orders ("Allow access to the microphone now!" says google Maps each time, although it doesn't need it, but someone at google wants to hear if there are any moans in my car, probably to delete them if considered inappropriate...) On the other hand, with my recent problems I use more time for the computer than the computer works for me :-( But that's off-off-topic. In regard to disk-labels: I label my external disks with useful names, but when I plug them by usb the message is only "1.8 TB encrypted drive". So if I connect several I never know which one is which, especially when I want to disconnect one to plug another one. Would be extremely nice if that box that opens when you plug a device would show it's name.

You have to label the filesystem inside the encrypted partition, and possible the partlabel outside. It might be possible to label the partition outside, before encryption, but then it may be overwritten and lost. The external uuid keeps, though. Maybe. I mount them manually, mostly, thus I define the directory where they mount. You need to define entries in fstab and crypttab for each disk (nofail,noauto). But then entering the password becomes one more nuisance than leaving it on automatic... So I wrote my own scripts. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
