Missing Linux features, missing features in LinuxFormat, missing our Dell XPS 13 and more missing!
Way back in the 1990s I developed TheDigitalDJDance Manager, which ran on a PC with Windows XP Pro. While it was written using Visual Basic 6 I would like to clean it up and rewrite it to run on Linux. The unfortunate thing is that this program enables one to use seven simultaneous displays, which isn’t easily done with any of the Linux distros I’ve seen.
While the current release of DJ isn’t pretty, it does get around the irritations which the use of Tabs pose when using an iPad! One display with tabs is not conducive to programs like this, or for businesses such as stocktaking, banking, purchasing and particularly like multidisplay video gaming.
When is Linux going to make it easier to add multiple displays to its otherwise powerful system? I’ve regularly had to use Windows when setting up multi-display systems for use by all of my business clients – they’re addicted to having more that two displays.
Another valuable product that seems to be Windows and Apple unique is called a Wormhole! This enables one to easily connect two different systems together via the USB port and have them work as a single computer from just one of their keyboards and trackball. Electro Group, via email Neil says: The classic Achilles’ heel of Linux is where the hardware and software worlds meet. Both the things you mention here really aren’t features, but products offered through hardware vendors.
The Wormhole is the easiest to address, I’ve never come across this, but it looks similar to the USB Direct Cable Connection that Windows used to offer to migrate installs, made obsolete by a networked option. Really, you’re asking the company to support Linux with its proprietary cable solution. Much of what you’re after would be achieved using a remote desktop solution such as TightVNC, which enables live screen/mouse/keyboard capture plus drag-and-drop sharing.
As for multiple monitors, from what I can tell X11 has supported multiple GPUs with xrandr since v1.4 was released in early 2013, but this needs to go hand-in-hand with driver support, too. It’s not something we’ve tried but all the information does seem to imply Linux can power up to at least 10 displays (in all likelihood more), even across different GPU manufacturers, as long as you have the hardware to do so. Perhaps using proprietary drivers would make things easier?
