Re: su-to-root not working

Thanks for all the replies. I won't be back at my Linux PC for a couple of days, but will give the suggestions a try. pkexec on the command line didn't work. Perhaps the polkit change will do the job. The fact that Luckybackup doesn't install the super-user launcher anymore is a bug! It should be fi...

Re: Luckybackup super-user not available after install via Software Manager

i don't understand why you go out of your way to avoid using timeshift which is already provided for you and doesn't need much effort from the user. true that timeshift is mainly constructed to restore the user/root filesystem not the user/home but i have never needed to restore my personal files w...

su-to-root not working

I've been using luckybackup for the past few years. When it installs, it creates the following launcher entry to start as superuser: su-to-root -X -c /usr/bin/luckybackup This has worked fine until Linux Mint 18.3. Now with Linux Mint 19 it doesn't work, nor does any other option work :cry: . I trie...

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

BTW I am passing thru to a Windows 10 guest. Host OS will be /IS Linux of some sort. Most likely Mint 18.3 as 19 seems a bit to new and I don't want the hassle of messing with it to get it to work as I like .. I have rewritten much of the tutorial to reflect changes in Linux Mint 19.

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

Thanx for the Reply. I am making great progress with this now, I got to the TURINO boot screen but then it tries to do some PXE boot, and dumps me into the UEFI BIOS options. It does not seem to use the iso file i have specifed, i will keep messing with it .... I suppose the fact that the TURINO bo...

@bash64: That's great news. Thanks for sharing all your steps. Perseverance certainly pays! There is no way I could have helped you in this. I don't use the i915 driver (no internal GPU), no SeaBIOS either. I wonder if nomodeset is really all that is needed. Do you mind posting your qemu script file...

thanks, i upgraded the laptop to 32gb of ram. when running fallout 4 i gave it 20gb because the game was a huge resource hog. giving the machine all 4 cores with 8 threads was normal for me. i can reduce it for now. been trying endless seabios files. no luck yet. i'll wait a few weeks till i have t...

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

Hi bash64, This does sound annoying, especially if you don't have a (full) backup. One thing that sticks out is the qemu script: -smp 8,sockets=1,cores=4,threads=2 \ -m 20G \ It means that you pass 4 cores/8 threads to the VM, as well as 20 GB of memory. Seems rather a lot for a laptop and might pre...

Hello, I seem to have failed to click submit on my last post. I'll shorten it here: I installed linux mint 19 beta. I am getting kvm internal errors. Have you had time to look into this? I did not change my qemu setup in any way and it always worked. I keep my full setup on an external 1TB SSD incl...

Re: Random timestamp changes on read-only SAMBA share

Linux Mint is based on Ubuntu, but there are some differences. I don't know whether or not they have a bearing on your problem, though. My guess is that your Windows backup utility reads the Samba file attributes somewhat differently, or that they aren't exactly identical with the way Windows handle...

Re: Random timestamp changes on read-only SAMBA share

When you are sharing a Linux file system like ext4 using Samba, it's quite possible that not all file and directory attributes are shared. You may check to see if the Windows ACLs are supported, see https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs . Also look at http://pig.made...

Just a short update: 1. A good place to look for working VGA passthrough configurations is https://passthroughpo.st/vfio-increments/ . Not only gives this table a good overview of configurations that work, but it also lists some of the pitfalls and work-arounds. 2. Max Ehrlich is producing the lates...

Re: VM crashes host - need help diagnosing

I agree with the above - Windows 10 will not work with 2 Gig RAM, especially if you try to run Photoshop or Illustrator. You should give it 4 Gig RAM, at the least.

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

Nevermind. I figured it out. Haswell has a issue where hdmi sound is broken when iommu is enabled in grub. To fix it i put "intel_iommu=on,igfx_off". I did not realise at the time that this will in turn break pci passthrough. I got passthrough to work up to the point where the driver is installing ...
