20:44bugbyter: I want to make virtual monitor (for sharing through vnc). Is it possible? I have tried to google but found nothing.
21:05gnarface: bugbyter: i'm not sure, but it's easy to make your desktop have more space than there is on your screen
21:08gnarface: bugbyter: oh, and also it is easy to run more than one instance of Xorg concurrently. you don't actually need a head for every one.
21:09gnarface: bugbyter: and there's something called xnest i heard of to run an instance of Xorg in a window inside another instance of Xorg
21:09gnarface: bugbyter: anyway, i think what you want to do is easily accomplished using well-known techniques and you're just framing the question wrong, that's why your search is coming up blank
21:12gnarface: there's no need to make a "virtual monitor" because a monitor isn't actually a requirement for a desktop shared via vnc
21:15bugbyter: gnarface: thanks, for replay. I have fast desktop and old laptop. I want to redirect some additional screen space (i called it virtual monitor) from desktop to laptop through vnc, to emulate multihead or somthing like this.
21:17gnarface: bugbyter: yea, totally. that's what it vnc and Xorg do by default though. you don't need a monitor. :) just Xorg and your vnc server over ssh, or with an init script or something, then connect to the vnc server.
21:18gnarface: bugbyter: but, by the same token, it's easier to just add more virtual desktop space to the window manager installed on the desktop. the old laptop can serve non-graphical stuff much more usefully now for you than a spare desktop.
21:20gnarface: bugbyter: ... hmm, wait, maybe i've misunderstood what it is you're trying to do though. if you are actually trying to make the same Xorg screen reach across two machines, what you'd do instead is just run the vnc server on the fast desktop, and connect to that with the laptop in sharing-only mode
21:20gnarface: bugbyter: but in that second scenario, you'd still have to do the step of adding extra virtual desktop space to the fast desktop
21:21gnarface: bugbyter: i dunno. sounds fun either way :)
21:21gnarface: bugbyter: what window manager are you using?
21:21gnarface: some of them make the process of adding virtual desktop space easier than others
21:22bugbyter: i use awesome wm
21:23gnarface: i don't know much about it
21:23bugbyter: I just want to make my visiable work space bigger. Yes, I will run vnc server on desktop
21:24gnarface: check the docs
21:24gnarface: look for virtual desktop
21:24gnarface: it is not a given that it does do it
21:24gnarface: i know enlightenment, gnome, kde, and blackbox all do though, in various forms
21:25gnarface: but, if you make a static /etc/X11/xorg.conf you can actually specify a larger desktop size than screen resolution
21:25gnarface: that is actually allowed
21:25gnarface: then you can pan around with the mouse
21:26gnarface: though it might need a second option for that now, i'm not sure, but it used to be the default behavior
21:28bugbyter: it is not certainly that I want, but thanks anyway
21:33gnarface: if what you want is a way to extend the desktop of the fast computer across to the laptop but processes also move back and forth from the laptop to the desktop not just graphics, that i don't know how to do
21:34gnarface: as far as i know there is no solution for that in the wild
21:34gnarface: but i could be wrong
21:38bugbyter: No, I just want to emulate multihead for my desktop. Just like I have 2 monitor: one connected to desktop directly and second is my laptop display connected to desktop through vnc. Both screens should have individual workspace.
21:40bugbyter: And of course I should have access to both screens from desktop
21:41bugbyter: One mouse and keyboard for both screens, smth like this
21:46bugbyter: I have found one hack on ArchLinux forum. One use xrandr to create virtual monitor by adding a new mode to one of the disconnected displays. But it doesn't work for me, I get (EE) NOUVEAU(0): failed to set mode: Invalid argument
21:48gnarface: syntax error or invalid value maybe
21:49gnarface: that's the same settings you can put in your xorg.conf too
21:50gnarface: and what you're talking about sounds exactly like my second suggested solution, read it again
21:58bugbyter: hack works on my laptop, where I have ATI GPU. I have tried to use proprietary nvidia driver on desktop, with it hack just makes my screen wider so I can scroll it with mouse, but I want invisiable space behind screen border
22:00gnarface: the drivers all have different amounts of support for the different syntax and commands available through xrandr, so.. yea. that's a real thing. also remember, you have GPU RAM constraints on what sizes you can set, and some drivers don't allow arbitrary resolutinos.
22:07bugbyter: I have tried set the same resolution on HDMI-2 (virtual) which used for HDMI-1 (real monitor). Real monitor works on both HDMI with this resolution. But suspect that problem is near.
22:10gnarface: since it is HDMI, don't rule out the cable
22:10gnarface: make sure it is rated for whatever resolution you're setting
22:10gnarface: especially *refresh rate* at that resolution, both matter together
22:31gnarface: (i had a problem with a amazon.com branded cable that was rated for 1080p@60 but could only go up to 1080p@50)
