The small linux problem thread

That’s odd. My 580 shows up as a 470/480/570/580 in lspci. I wonder what’s going on there.

IIRC my old 390 showed up as a 290/290X.

yeah, my 380 is showing up as a 285/380.

Yeah, since they’re refreshes I don’t think they show up as proper, but under the hood they function just fine. Like the kernel module knows whats up.

Trying to make my monitor settings persistent after reboot by generating an xorg file. (This is the type of dumb shit I hate about linux)

For my 144hz monitors, xrandr reports 143.86 as the refresh rate.
When generating a modeline It reports a different number if i use 144 or 143.86.

$ cvt 2560 1440 144
# 2560x1440 143.91 Hz (CVT) hsync: 225.66 kHz; pclk: 808.75 MHz
Modeline "2560x1440_144.00"  808.75  2560 2792 3072 3584  1440 1443 1448 1568 -hsync +vsync

and…

$ cvt 2560 1440 143.86
# 2560x1440 143.83 Hz (CVT) hsync: 225.38 kHz; pclk: 807.75 MHz
Modeline "2560x1440_143.86"  807.75  2560 2792 3072 3584  1440 1443 1448 1567 -hsync +vsync

Is the inconsistency something I can ignore? Guess ill try them out and see what happens.

I’d ignore it.

Have you tried it?

Linux application windows stutter
Youtube video illustrates my problem. Does anybody have any suggestions?

what system specs you got?

I need to know a little something.

Does anyone know how to use the CLI to put the monitor to sleep? I want to bind this to a shortcut in i3wm on Xorg.

On Fedora 27 trying to make GNOME less painful. Installed Firefox GNOME extension, but it keeps telling me a I need a ‘native connector’. What it is a ‘native connector’ and where do I get it?

You have to install the following .rpm. I know it says, chrome but it will work with all browsers.

chrome-gnome-shell

The terminal. This small guide, should hopefully help.

I have a little issue.
I have a server running mint that shares folders. I want to mount those share on boot but for some reason its not mounting the share as writable and asking for my password.

The shares are open for read/write.

im running manjaro (arch)

fstab

# /etc/fstab: static file system information.

Use ‘blkid’ to print the universally unique identifier for a device; this may

be used with UUID= as a more robust way to name devices that works even if

disks are added and removed. See fstab(5).

UUID=C524-90F2 /boot/efi vfat defaults,noati$

Hello everyone,

I am currently trying to figure out a way to add a custom boot option on Grub. I am running Fedora 27 on my system.

My goal is to have a custom boot option that binds my Nvidia GPU to vfio-pci. However, I don’t always want to do this since my machine is a Linux Gaming machine first. So I want to default boot option to not isolate the GPU but have the option to if I want to practice isolating the GPU.

I did some research and figured out that you add a custom boot option on /etc/grub.d/40_custom. I also understand that the way you provide the boot options is different from what you supply on /etc/default/grub.

Arch Linux provides a good example of how a custom menu entry would look like. But the part I am confused on is where one would put the options listed in GRUB_CMDLINE_LINUX.

Maybe try something like this format in your fstab:

//servername/sharename /media/windowsshare cifs guest,uid=1000,iocharset=utf8 0 0

Got from: https://wiki.ubuntu.com/MountWindowsSharesPermanently

I know I had a terrible time getting the right settings set for my NFS shares. They still don’t work quite right.

I believe that those go in the grub file in the “/etc/default” directory.

Thank you for replying.

Unless I am misunderstanding, I believe /etc/default/grub would also affect the default boot option, which I don’t want to change.

I want there to the be two boot options, the default boot option, being "Normal Linux Gaming Day" and a second option, bring "VFIO Party Island Adventures".


Edit: I feel silly not thinking about this… /boot/efi/EFI/fedora/grub.cfg contains the menu entries that are seen on the boot screen. I could just copy the menuentry and add-on the additional vfio-pci parameter.

But to answer my previous question, the options in GRUB_CMDLINE_LINUX seem to be applied to the linuxefi section, but not in the same order…

cheers mate.
That got the mounts to mount with read/write but not mounting at startup.

Nothing a mount -a doesnt fix though.

At that same link there’s a sort of troubleshooting section at the bottom. One of the problem/solutions is that it won’t automount at startup. The suggestion is to use username=guest,password= instead of guest. You could give it a try, might be one of those weird situations. You could also try to add auto in there, too. My fstab (which is set up for NFS, not Samba, but it’s similar) doesn’t need auto, and it mounts automatically every bootup anyway. Not sure.
