Ahem, love. I haven't yet fully grasped why some commands behave different as they do when from dom0, compared to when same command is executed inside the AppVM. For example the bash example above. But I imagine, grasping this difference, one can probably execute anything from dom0. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

I do something very similar for my QubesTV setup that I'm working on polishing, which works on scripts too, like we're doing here. The command may have to be adjusted a bit, but in general, it should work, even without xclip in dom0. Actually, I'd go as far as to say it should most definitely work for xclip, while my scripts here are different, I've done it enough to tell it can work if modified correctly. Either way, try awokd's command out, it will definitely work in one variant or different. The question is if require a bit of modification. For example, maybe use "qvm-run AppVM bash 'command to execute inside AppVM -o etc. lalala'" instead of say, "qvm-run AppVM gnome-terminal -e 'command to execute inside AppVM -o etc. lalala'". For example I've seen a case where one when executed inside the AppVM, will open the executed QubesTV streaming link in the same browser, same tab, while the very same command inserted into the AppVM from dom0, would open up a whole new instance of Firefox, and thereby open a new window. Which, needless to say, doesn't work. The solution was to use bash for already running firefox, so that it won't start a new firefox instance. Hopefully you can use any of this to make qvm-run appvm "command" work. In terms of security, I'm in the same boat, I can't say for sure. But I agree with the notion, that it "probably"? is secure due to the one direction flow of data. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

In dom0 you are only using gnome-screenshot to make the screenshot. If it is not available in dom0 you can install it via qubes-dom0-update gnome-screenshot or use any other existing sxreenshot-app which is available in your dom0 and offers the option to safe screenshots directly to file. Question regarding security: As far as I can tell I don't think that the suggested solution to transfer screenshots to an AppVM offers a great security risk as the data is only flowing from (!) dom0 to your AppVM and the graphic file is creating in dom0. But as I am far away from being a security expert, I'd like to hear a more qualified feedback if working with this script might be a bad idea.

[qubes-users] Q4rc4 :: SUCCESS qvm-screenshot-to-clipboard - 1st working version 0.1
Hello, after some troubleshooting I can now present a working alpha-solution for copy & paste screenshots between dom0 and AppVMs. You might have to install 2 packages: xclip in your AppVM gnome-screenshot in dom0 I had to tweak the xclip command a bit and now the script does exactly what it should do. You also don't need to have a helper script within the AppVMs, just copy the script to dom0 and launch it with: qvm-screenshot-to-clipboard Then choose the area you want to screenshot and switch to your AppVM and paste it. There is an effect that the xclip command will wait until you pasted the image before the script continues. But this is a nice thing as you can get two notification: 1) Screenshot is available in AppVMs Clipboard 2) Screennshot has been pasted from AppVMs clipboard. Attention: This script has mainly be made to provide a quick workarround and to get inter-VM screenshots working. There is much improvement for error detection and also mabye usability improvements that the script can be launched without a command line argument, presenting a popup after the screenshot to which AppVM the screenshot should be placed. Feel free to improve this, I'll upload the code to GitHub. regards [799] the script follows here --- #!/bin/bash # qvm-screenshot-to-clipboard # Creates a dom0 screenshot and copy it to the Clipboard of an AppVM # Define Variables MyAppVM=$1 MyScreenshot=qvm-screenshot-to-clipboard.png # Take screenshot in dom0 by selecting an area and adding border+shadow gnome-screenshot --area --include-border --border-effect=shadow --file=/tmp/$MyScreenshot # Copy screenhot to AppVM qvm-move-to-vm $MyAppVM /tmp/$MyScreenshot # Create a helper-Script in the AppVM to copy screenshot file to clipboard echo "xclip -selection clipboard -l 1 -t image/png /home/user/QubesIncoming/dom0/$MyScreenshot" > /tmp/file2clipboard.sh chmod +x /tmp/file2clipboard.sh qvm-move-to-vm $MyAppVM /tmp/file2clipboard.sh # Send notification for 5sec when Screenshot has been pasted into (!)

[qubes-users] Q4rc4 :: qvm-prefs-screenshot-to-clipboard - 1st attempt
Hello, having the idea of a qvm-screenshot-to-clipboard script I was eager to try writting a script. The solution I had in mind could work but I am struggling with a small issue and would like to get some help. The script takes a screenshot in dom0, store it to a file and qvm-copy the file to the target appvm (one and only command line argument for the script). Then within the AppVM it is using xclip to copy the graphic to clipboard and removes all temporary files in the AppVM and dom0 All pieces are working, except the xclip command when launced from dom0. When I launch the command within the AppVM it is working. But I need to start the xclip command from an external script and when I do so, the same command is not working. It seems that I am missing something when using xclip via script which is run in a new terminal session (from dom0 but also within the App) Any ideas how to fix this? It feels so frustrating that I nearly have a working solution but I am missing the last few meters. How to use the script: 1) in dom0: launch script 2) make the screenshot by selection the area as the xclip is not working in the AppVM as supposed: 3) switch to the AppVM where the screenshot should be used 4) launch the "helper script" in the AppVM which is running the following command xclip -selection clipboard -t image/png /home/user/QubesIncoming/dom0/qvm-screenshot-to-clipboard.png My qvm-screenshot-to-clipboard script which has to be placed and run from dom0: --- BEGIN of script --- #!/bin/bash # qvm-screenshot-to-clipboard # Creates a dom0 screenshot and copy it to the Clipboard of an AppVM MyAppVM=$1 MyScreenshot=qvm-screenshot-to-clipboard.png # Take screenshot in dom0 by selecting an area and adding border+shadow gnome-screenshot --area --include-border --border-effect=shadow --file=/tmp/$MyScreenshot # Copy screenhot to AppVM command line argument / delete existing file qvm-run $MyAppVM 'rm -f /home/user/QubesIncoming/dom0/$MyScreenshot' qvm-copy-to-vm $MyAppVM /tmp/$MyScreenshot ###FIXME begin # I would like to just invoke the following # command via qvm-run in the AppVM # but the clipboard is just empty when using # this approach. # running the same command # xclip -selection clipboard -t image/png /home/user/QubesIncoming/dom0/qvm-screenshot-to-clipboard.png # therof I have put the command into a helper # script in my AppVM: # qvm-run $MyAppVM /home/user/qvm-screenshot-to-clipboard-appvm.sh # the script is working when it is launched from # an already opened gnome-terminal window # but it will not work when the script is invoked # from dom0 via qvm-run or through an own # strangely it is also not working when I start # the script from within the appvm # 'xterm -e -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Q4rc4 :: qvm-screenshot-to-clipboard (Was: Q4rc4 :: AppVM Screenshot-Tool only generates black window)
Hello, I have made some research and it seems that it is not possible to make screenshots within one AppVM but only from dom0. Having a short walk in our forest I came up with a great idea (at I think it is :-) which I would like to share to hear your opinions. I know that there are some screenshot tools for Qubes like the qvm-screenshot-tool, which are trying to make the screenshot workflow easier when taking screenshots from dom0. https://github.com/evadogstar/qvm-screenshot-tool/blob/master/README.md I would like to have a tool, which makes a screenshot on dom0 (select area which should be screenshoted) then save this to a file, which gets qvm-copied to the AppVM I need the screenshot on and then copy the graphic file into the clipboard and delete the file afterwards. This would make the workflow working with screenshots much easier. It seems that something like "copy graphic file to clipboard" can be done: https://askubuntu.com/questions/759651/how-to-copy-an-image-to-the-clipboard-from-a-file-using-command-line xclip -selection clipboard -t image/png -i example.png Can someone build a script in dom0 to do this? qvm-screenshot-to-appvm-clip - start 1) command to open a screenshot tool in dom0 with the possibility to select an area of the screen and make a screenshot. 2) after the taking the screenshot the screenshot is saved to a file on dom0 (/tmp/screenshot-.PNG 3) qvm-copy-to-appvm /tmp/screenshot-.PNG 4) qvm-run "copy-picture-to-clipboard.sh screenshot-.PNG" 5) copy-picture-to-clipboard.sh is a script in the AppVM which copy the file from the Qubes-Incoming/dom0 directory into the clipboard Maybe something like xclip mentioned here: https://askubuntu.com/questions/759651/how-to-copy-an-image-to-the-clipboard-from-a-file-using-command-line 6) delete the screenshot in the AppVm 7) delete the screenshot in dom0 - end What do you think? Wouldn't this feature be a great enhancement for working with Qubes?

[qubes-users] Q4rc4 :: Fedora AppVM Screenshot-Tool only generates black window

I am using a Fedora 26 AppVM based on the default Fedora template which comes with Qubes 4rc4. I have updated the template to the latest version.

I also noticed similar slowdowns. I have no experience with rc3 (upgraded directly from 3.2), but your numbers seem to councide with my experience. Hardware is also pretty similar, namely Z170/6700K. --WillyPillow -- https://blog.nerde.pw/ PGP fingerprint = 6CCF 3FC7 32AC 9D83 D154 217F 1C16 C70E E7C3 1C8 -- -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Re: [qubes-users] q4rc4 very slow. VMs take 23 - 33 seconds to start
pvh. the hvm ones took even longer. looked at a couple systemd-analyze, one of them had 10s for dkms and 40 for qubes-update-check, even though that one only took 25s to boot, at least according to dom0. could whatever tells dom0 a guest is up have run before that? will play with this more and get back to you. turns out the qvm-pref debug doesnt matter in boot time. its hvm that takes around 40 seconds, and pvh that takes around 25. a standalone hvm with no os installed took 16 seconds to "start" this started happening after installing 4.0rc4 over 4.0rc3. had to qvm-prefs the restored vms to pvh. at first i thought it was just the performance hit from mitigating speculation vulnerabilities, but others were reporting better performance in rc4 than rc3. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
