Greetings, Call me old fashioned, but I run startx manually and I have an .xinitrc file. In that file, I run setxkbmap, xset, and xinput to set up my keyboard and my trackpad. This has been working for years, across three consecutive laptops, with minor adjustments to the parameters and input device names. A few weeks or a month ago, some system upgrades (i.e., pacman -S ...) reset those settings. The symptoms are an extremely slow trackpad and the default keyboard layout (dead keys and all). If I re-run the configuration commands from my .xinitrc file, all is well. It's hard to tell exactly which part of the process resets my settings, but I'm pretty sure it's during the post-transaction hooks, possibly around step 5/7 Updating module dependencies, or near the beginning of step 6/7 updating linux initcpios. It only happens when pacman rebuilds my kernel; at first, I thought it was tied to systemd upgrades, but it happened this morning, and there is no systemd upgrade. I run a stock kernel with liitle no customization. So far, none of the upgrades have failed, and I've not had problems rebooting with the new kernels. I do see entries in Xorg.0.log related to input devices from around that time, but I can't correlate those entries with the output from pacman. I hope the relevant section is below. Any thoughts? What other information can I provide? What experiments can I run?
