[qubes-users] Switching desktops causes stuck ctrl key
For the last month or so, I've been having a problem -- intermittently, when I switch desktops using Ctrl+Alt+arrow key, I find that on the new desktop all applications behave as if the Ctrl key is stuck, constantly pressed down. For instance, if I start scrolling the mouse in Firefox, I will start zooming in and out on the page. Experimentally, I can usually clear the stuck key by switching back and forth to another desktop a few more times. Has anyone else encountered this? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Re: [qubes-users] Troubleshooting an AppVM that suddenly can't connect to the network
Thanks, you are right that I don't have any experience with packet sniffing, however, after making sure that nothing else was using the network and running iptables -L -nvZ on both sys-net and sys-firewall... there's no packets at all getting there from this AppVM. Which doesn't make any sense to me, the default route is definitely there: $ ip r default via 10.137.0.6 dev eth0 10.137.0.6 dev eth0 scope link and in qvm-firewall both DNS and ICMP are allowed, yet neither is working. Is there more debugging I can do on the AppVM itself? Both sys-net and sys-firewall are based on the fedora-30 template. There is only one AppVM affected, all others based on the same template are working fine. In fact, I copied the complete contents of the bad AppVM's home directory to a new AppVM, and it's also having no problems connecting to the network. I would like to find the root cause, but that's my workaround for now. Thanks for any more advice you can offer.

[qubes-users] Troubleshooting an AppVM that suddenly can't connect to the network
I'm having a problem that I'm very confused about. I have several AppVMs based on the same fedora-30 TemplateVM. Some of them are completely cut off from the Internet, some have firewall restrictions, some connect through sys-firewall but are not restricted. Today, one specific AppVM has started refusing to connect to anything. Even if I try to connect by IP address, it claims it can't route. Example: $ ssh user@192.168.34.22 ssh: connect to host 192.168.34.22 port 22: No route to host $ ip r default via 10.137.0.6 dev eth0 10.137.0.6 dev eth0 scope link I've gone through the few settings and error logs that I can think of, but nothing seems to be unusual about this particular AppVM. I've checked qvm-firewall and the rules should be allowing appropriate traffic to pass. I have not changed any settings. I have tried rebooting the system once or twice as well, with no effect. It seems like I can get to sys-firewall across the link-local connection, but that's all. After that, nothing seems to work. Every other AppVM I've tried is working fine. Where should I be looking next? Thank you. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Re: Instability with video and graphics in fedora-30
I thought that I would follow up and note that performance has gotten significantly better during the last month after applying package updates. I don't know which package upgrade specifically fixed things; there have been multiple kernel, Xorg, and graphics-related package updates in that time.

[qubes-users] Instability with video and graphics in fedora-30
Hi, I've recently updated to a fedora-30 + rpmfusion template for many of my AppVMs. I've begun to experience a lot of instability in the following situations: * mpv playing video (often segfaults even before playback starts) * vlc playing video (often segfaults before playback starts) * Firefox rendering Google Maps -- I suspect this uses WebGL? (performance significantly degraded, occasionally the browser locks up) * Firefox rendering video (occasionally the browser stops responding) I double-checked my dom0 configuration against this page: https://www.qubes-os.org/doc/intel-igfx-troubleshooting/ and in fact I even switched from the Xorg Intel driver to the modesetting driver (see https://github.com/QubesOS/qubes-issues/issues/4782) after I noticed from the Xorg log that there seemed to be some issues with my graphics card and the Intel driver. That didn't make much of a difference. I've confirmed that it's something in the template: if I switch those AppVMs back to fedora-29 + rpmfusion, the problems go away. However I'm not really sure where to look from here to continue debugging. I'd appreciate any advice.
