[01:03] <PeGaSuS> I have an Ubuntu server installed on a laptop. the laptop screen is broken so I have an external monitor. but things aren't being displayed properly, because the left is missing some letters. can I do something about it?
[01:14] <JanC> PeGaSuS: what sort of monitor?
[01:20] <PeGaSuS> a normal one? those one connected via VGA. hitting the auto button does nothing
[01:23] <JanC> it sounds like an old CRT monitor problem with unsupported resolution  ;)
[01:24] <PeGaSuS> it's an LCD monitor though
[01:25] <PeGaSuS> CRT monitors aren't "normal"
[01:25] <PeGaSuS> this one, actually: https://complete-it.co.za/r2/monitors/407-refurb-philips-196v-led-monitor-19.html
[01:27] <PeGaSuS> apparently it's LED
[01:27] <JanC> anyway, do you really need to see anything on it for a server?
[01:28] <JanC> "LED" just means it uses LEDs as a backlight really (which is standard now)
[01:30] <JanC> once it's installed, you should be able to manage the server over SSH (or a web interface if you prefer that)
[01:30] <PeGaSuS> if I restart with monitor attached, all is displayed properly. if I restart it without the monitor attached, then I have dissplay issues. and yes, it's a home server, I need to have a monitor attached from time to time
[01:32] <JanC> okay, so that's because it's connected through VGA
[01:32] <PeGaSuS> unfortunately the HDMI port is busted
[01:33] <PeGaSuS> I was about to throw the laptop to th garbage. I decided to refurbish it as a home server
[01:33] <PeGaSuS> it is like 12y old already, although it was a good laptop back in the days
[01:34] <JanC> it was a common problem before digital connectors existed, as the graphics card can't detect that there is no monitor or a new one
[01:34] <JanC> (VGA in analogue)
[01:34] <PeGaSuS> yeah, I suspected that much. I assume I can't just tell the OS to "redraw"?
[01:36] <JanC> is this in the console?
[01:38] <PeGaSuS> yes. there's no DE installed. it's just a fresh regular Ubuntu Server install with the exception that I sometimes will need to attach a monitor and I may have rebooted the server without the monitor attached which will break displaying
[01:39] <PeGaSuS> I was expecting of a way to tell the server "hey, you have a monitor attached now, please redraw displaying"
[01:41] <JanC> I think part of the problem is that nowadays Ubuntu boots with a graphical console; maybe disabling the graphical console & booting in text mode would work...
[01:42] <JanC> but I forgot how to do that  :)
[01:46] <PeGaSuS> I think that I have a VGA switch somewhere. so I can have my desktop and the server attached to the same monitor
[01:47] <JanC> that usually doesn't help when you boot the server while it's switched to your desktop...
[01:52] <PeGaSuS> I'll live with it as it is
[01:52] <PeGaSuS> :D
[01:54] <JanC> maybe one of the GRUB_TERMINAL or GRUB_GFXMODE options in /etc/default/grub will work?
[01:55] <JanC> although that only applies to grub, and not the kernel, I suppose
[01:56] <JanC> oh, wait, and/or maybe try to add 'nomodeset' to GRUB_CMDLINE_LINUX_DEFAULT in that file
[01:57] <PeGaSuS> I mean, I'll rarely reboot the system while the screen is not attached. but I was just trying to see if there was another way
[01:57] <JanC> also see /usr/share/doc/linux-doc/admin-guide/edid.rst
[01:58] <PeGaSuS> I'll poke around it, thanks!
[02:01] <JanC> and maybe vbetool can change video modes (but it might only work in BIOS mode, not sure it works in UEFI mode?)

[06:33] <wharfrat1> ,
[11:26] <Haris_> hello all
[11:26] <Haris_> I have a ubuntu vm on vmware with single volume. this vol is 18G. Its LVM based. I extend this disk to 40G. Then I do the lvm extend part. for some reason the lvmextend doesn't go right. Is there a way to access this volume? on reboot the linux vm says it can't find this volume
[11:27] <Haris_> When the root volume is not available, can one boot the VM in recovery mode? may be resize the volume or resize the volume back to its original extents?
[11:28] <Haris_> this VM is on vmware based platform
[11:37] <Haris_> how to re-scan for available disk volumes on ubuntu focal?
[17:10] <Walex> depends on the type of volume. Anyhow try 'udevadm trigger' and 'rescan-scsi-bus.sh'
[17:10] <Walex> Haris_: did you actually extend the volume at the VMware level?
