so you did not follow the instructions to install bumblebee given in the link provided by ozeszty? did you try to add nomodeset to the kernel command line as I suggested?

do you have an integrated intel GPU also and can you disable it in BIOS? you could try to add 'nomodeset' to the kernel command line for testing..

Thx a lot for your suggestions.. tried but upon rpmrebuild (in a fresh Fedora 27 VM) I get the error "configure: error: Compiler GCC >= 4.7 or Clang >= 3.3 is required for C++ compilation" although I have gcc installed, "gcc -v" gives: "gcc version 7.3.1 20180130 (Red Hat 7.3.1-2) (GCC)"

2018-02-17 03:55:14 -0500 asked a question Upgrade to Fedora 27 - no webkitgtk - what are my options?

Hi there,

planning to upgrade to Fedora 27 I noticed that webkitgtk has been removed for security reasons. I still would like to use a sysml modelling tool called Modelio, which unfortunately depends on webkitgtk..

What are my options?

Thx & cheers

-1908 is the most common error and mostly relates to an incomplete or flawed installation of VirtualBox. You like to read the following installation tips over here and see if you missed crucial steps (UEFI secure boot enabled?):

2017-07-02 05:33:37 -0500 commented question VM autostart fails because bridge interface is not ready

well well.. from I got that I can enable the service "systemd-networkd-wait-online" but as explicitly stated there, this might considerably delay the boot of the whole system and thus is discouraged as a general procedure.. still looking for a solution to limit this to the scope of "vm attached interfaces" only..

2017-07-02 02:55:58 -0500 commented question VM autostart fails because bridge interface is not ready

ok got the automatic shutdown part solved by enabling the libvirt-guests service and modifying the '/etc/sysconfig/libvirt-guests' appropriately.. libvirt-guests can also deal with the automatic start of VMs, but the same problems remain, that the used bridge interface is not up yet and thus the VM domain fails to start.. :(

2017-07-02 01:50:25 -0500 asked a question VM autostart fails because bridge interface is not ready

Hi there,

I want to have have several VMs powered up automatically on host boot, but that fails because during host boot the dedicated bridge-interface is not ready yet - log output from libvirtd:

Jul 02 07:54:27 saba1 libvirtd[1337]: Preferred CPU model cpu64-rhel6 not allowed by hypervisor; closest supported model will be used

Jul 02 07:54:28 saba1 dnsmasq[1851]: reading /etc/resolv.conf
Jul 02 07:54:28 saba1 dnsmasq[1851]: using nameserver

How can I ensure that the VM startup is delayed until all network interfaces are up?

And on a side question: when the host is instructed to shut down, how do I properly power off all the VMs automatically - is there some kind of shutdown-script I have to modify?

Thx and cheers!

well "sudo <command>" means to acquire root priviliges for the command to be executed. It should have asked you for your password to verify that you are in the "sudoers" list (in which only the root user may have put you). If you are not entitled to gain root priviliges, you cant have executed "grub2-mkconfig".

2016-12-06 15:45:25 -0500 commented answer Recovering admin password

what do you mean with ".. grub is not locked" ?

2016-12-05 14:04:46 -0500 answered a question Recovering admin password

Using grub:

  1. select the appropriate boot entry, then press 'e'
  2. look for the line that starts with "linux" or "linux16" (for uefi: "linuxefi")
  3. place the cursor at the end of that line, append "<space>rw<space>init=/bin/bash" (without quotes)
  4. hit Ctrl-x and the system will boot with root to bash
  5. enter "passwd", enter new password (twice)
  6. to make selinux happy: enter "touch /.autorelabel"
  7. reboot: "/sbin/reboot -f"

Remember: with great power comes great responsibility.

2016-02-06 18:08:51 -0500 commented answer Remove/Uninstall tracker

well actually this will still report that dependency-packages will be removed like "brasero", "gnome-boxes", etc.. so no, this did not the trick.

2016-02-06 03:53:44 -0500 asked a question Remove/Uninstall tracker

I want to get rid of tracker. How do I safely remove it (i.e. tracker, tracker-needle, tracker-preferences)?

When I do

dnf remove tracker-1.6.1-1.fc23.x86_64

dnf lists a ton of other dependency-packages to be removed (e.g. qemu-* etc.) which I definitely want to keep.

Any advice appreciated.. thx.

2016-01-30 15:43:23 -0500 answered a question Cannot "startx" after kernel upgrades

boot your newly installed kernel to runlevel 3, then as root remove the akmod nvidia package with

dnf remove akmod-nvidia

reboot to runlevel 3 again, check if you can 'startx' (using VESA or, if still present, nouveau).

then you may try to reinstall akmod-nvidia package.

I have this issue from time to time and usually it solves it for me.

2015-10-22 15:57:48 -0500 asked a question GDM asks for root password on shutdown/restart

Hi there,

since I upgraded from Fedora 21 -> 22 I can no longer shutdown/restart from the GDM login screen without providing the root password.

Can anyone tell me why that is and how I could correct that, so that I can shutdown/restart from GDM login screen without needing to provide the root password ?

2015-04-18 17:30:31 -0500 commented answer Steam on Fedora 21: OpenGL GLX error

@Bijju: the OP stated that all 32bit games fail to run, this implies 64bit would be working. Hence installing the 32bit xorg driver is obvious. @Warren: you're welcome. On my system (Fedora 21 64bit) I did not need to carry out any of the other mentioned steps. besides the currently most voted solution to delete libstd* and libgcc* files seems not to be a good solution.
