  • What timing, after seeing the news about Windows 12 yesterday, this morning I was considering starting a conversation with the researchers at work about pressuring the scientific instrument companies they buy from to support Linux. The one facility in the building that has Bruker instruments runs AlmaLinux, and they’ve been spared from all the pain.


  • That looks like it should work. Just a couple of thoughts: The default gateway is irrelevant. That’s only where the OS sends packets that don’t match the netmask. Since these addresses all lie within the same /24 range, the default gateway will never be used. It wouldn’t hurt to check the ARP tables of each OS to see whether the VM MACs ever show up on the remote host or VM. Are the two hosts connected with a cable, or via WiFi? If the latter, VirtualBox has to do some software trickery to make bridging work, and I can imagine that perhaps some WiFi devices wouldn’t play nice.


  • I saw that post, and honestly, part of the issue is that the pain of messing with mode-lines in /etc/XF86Config and worrying about physically damaging your CRT monitor with out-of-spec frequencies was a very real thing 30 years ago. Hence, the idea that configuring displays on Linux is fraught and difficult has stuck around, even though it hasn’t been true since the advent of DDC, and multiple displays for most use-cases has been sorted out for at least the past 15 years. Non-Linux users will still occasionally talk about displays on Linux as if we were still editing mode-lines in vi.

    It’s a sore point, I guess I’m saying, and you poked it inadvertently. When I read the post, I just kind of smiled, because a few days before, I plugged the HDMI cable from a conference room display into my Thinkpad, and it lit up with an extension of my desktop. I started LibreOffice Impress, hit ‘F5’, and the presentation appeared on the big display, and the presentation notes on my laptop screen. (Actually, I was surprised and impressed at how smoothly it went.)

    It’s no surprise that issues remain here and there, though. Glad to hear that folks wanted to be helpful!
