Since then I rarely encounter the lagging cursor. If I open Settings > Mouse & Touchpad and toggle any option on/off the cursor starts lagging. How can make the cursor work reliably?

[Ubuntustudio-bugs] [Bug 1787857] Re: USB mouse cursor lags after random time of correct behaviour
In my case with Parrot Linux it was a case of Interrupt conflicts. IRQ#18 kept being disabled by the system. After disabling the EHCI Handoff in the BIOS,ehci_hcd:usb1 was replaced with ehci_hcd:usb2 and the mouse lag after a random period of time stopped. You can view your interrupt assignments with: cat /proc/interrupts Mine changed from: 18: IO-APIC 18-fasteoi ehci_hcd:usb1, pata_jmicron, ata_piix, uhci_hcd:usb8 to: 18: IO-APIC 18-fasteoi ehci_hcd:usb2, pata_jmicron, ata_piix, uhci_hcd:usb8 And the problem was resolved. -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to rtirq in Ubuntu.

[Ubuntustudio-bugs] [Bug 418242] Re: Incorrect call to output plugins (with persistent error message) on copy
** Changed in: inkscape (Debian) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to inkscape in Ubuntu. Matching subscriptions: Ubuntu Studio Bugs https://bugs.launchpad.net/bugs/418242 Title: Incorrect call to output plugins (with persistent error message) on copy Status in Inkscape: Invalid Status in inkscape package in Ubuntu: Triaged Status in inkscape package in Arch Linux: New Status in inkscape package in Debian: Fix Released Status in Gentoo Linux: Unknown Bug description: UPDATE: After further investigation it turned out to be a problem related to the copy operation, in combination with a totally unrelated running Java program (FreeRapid). Reading some followups and other bug reports, it seems to be caused by the new clipboard management system (introduced as a fix for the bug #170185), as reported in bug #421597. The routine ClipboardManagerImpl::_onGet is called repeatedly by an external program, with different possible clipboard formats, causing Inkscape to try and export the copied data every few seconds, in multiple formats. So far these applications are known to randomly trigger an input/output extension (on linux): - FreeRapid Downloader - jDownloader - xfce4-clipman-plugin 1.1.3 - Netbeans - xfce4-settings-helper (Xfce 4.8) - Team Viewer (teamviewerd 10.0.36) Workaround - disable offending output/export plugins (comment #87) - The original report was this: I'm getting this error when I try to edit a text object created previously with a font that's not available in this system. It looks like Inkscape has problems to resolve the font substitution and displays the error message in a popup window that keeps appearing again and again, leaving no other remedy than closing inkscape and reopening it. The error message is attached.
