--- Comment #9 from Peter C B Henderson <peter.hender...@ieee.org> --- As stated in my previous comment (2019-02-03 09:52:33 UTC), installing the nvidia driver fixed the problem. Nevertheless, to help identify what caused it in the first place I started the regression of mesa-dri, as suggested by Jan Beich (2019-02-03 12:32:44 UTC). The first step was to delete the nvidia packages I had installed, i.e. nvidia-driver-340-340.107_3, nvidia-settings-415.25 and nvidia-xconfig-415.25. I rebooted and then checked to see if the problem had returned. To my surprise, everything seemed to work as it should. Application menus worked normally. The strange forbidden region of the screen (see my comment 2019-02-03 03:25:47 UTC) didn't manifest itself. To see if I could recreate the problem, I then removed the linux compatibility packages installed when I installed the nvidia driver, i.e. linux-c6-expat-2.0.1_5, linux-c6-fontconfig-2.8.0_3, linux-c6-xorg-libs-7.4_10 and linux_base-c6-6.10. Again, I rebooted to see if the problem had returned. Again, everything was, and still is, working normally. Note, these were the only linux compatibility packages on my system. As a result, I'd like to know if there is still any point in regressing mesa-dri as suggested by Jan Beich? I'm actually not sure if I can perform this regression. FYI, I have included a list of all the upgrades I have done since this problem appeared. None of them in themselves fixed the problem, but they may have some bearing on why it has not reappeared. apache-openoffice-4.1.6_3 -> apache-openoffice-4.1.6_4 bash-5.0_2 -> bash-5.0.2 binutils-2.30_7,1 -> binutils-2.31.1_1,1 ca_root_nss-3.41 -> ca_root_nss-3.42 cmake-3.13.2 -> cmake-3.13.3 droid-fonts-ttf-20131024_3 -> droid-fonts-ttf-20131024_4 emacs-26.1_4,3 -> emacs-26.1_5,3 firefox-64.0.2_1,1 -> firefox-65.0_1,1 gnutls-3.6.5_1 -> gnutls-3.6.6 gsed-4.2.2_2 -> gsed-4.7 harfbuzz-2.3.0 -> harfbuzz-2.3.1 harfbuzz-icu-2.3.0 -> harfbuzz-icu-2.3.1 hunspell-1.6.2_2 -> hunspell-1.7.0 java-zoneinfo-2018.g -> java-zoneinfo-2018.i kf5-sonnet-5.54.0_1 -> kf5-sonnet-5.54.0_2 krdc-18.12.1_1 -> krdc-18.12.1_2 -> libchk-1.10.3 (newly installed package) libedit-3.1.20170329_2,1 -> libedit-3.1.20181209_2,1 libgit2-0.27.7 -> libgit2-0.27.8 libgpg-error-1.34 -> libgpg-error-1.35 libinput-1.11.3_1 -> libinput-1.12.6 libnghttp2-1.35.1 -> libnghttp2-1.36.0 libssh-0.8.4 -> libssh-0.8.6 libssh2-1.8.0,3 -> libssh2-1.8.0_1,3 libuv-1.24.1 -> libuv-1.25.0 libva-2.3.0_5 -> libva-2.4.0 libvncserver-0.9.11_2 -> libvncserver-0.9.12_1 libxkbcommon-0.8.0 -> libxkbcommon-0.8.0_1 mysql56-client-5.6.42_1 -> mysql56-client-5.6.43 mysql56-server-5.6.42_2 -> mysql56-server-5.6.43 mythes-1.2.4_5 -> mythes-1.2.4_6 node-11.6.0 -> node-11.8.0 nss-3.41_1 -> nss-3.42 okular-18.12.1_1 -> okular-18.12.1_2 p11-kit-0.23.14 -> p11-kit-0.23.15 pciids-20181228 -> pciids-20190120 pkgconf-1.5.4,1 -> pkgconf-1.6.0,1 plasma5-kdeplasma-addons-5.14.5_1 -> plasma5-kdeplasma-addons-5.14.5_2 py27-beaker-1.10.0 -> py27-beaker-1.10.0_1 py27-pytz-2018.7,1 -> py27-pytz-2018.9,1 py27-requests-2.18.4_1 -> py27-requests-2.21.0 py27-setuptools-40.6.2 -> py27-setuptools-40.6.3 py27-setuptools_scm-1.17.0 -> py27-setuptools_scm-3.1.0 py36-setuptools-40.6.2 -> py36-setuptools-40.6.3 qt5-virtualkeyboard-5.12.0_1 -> qt5-virtualkeyboard-5.12.0_2 re2-20180901_1 -> re2-20190101 rust-cbindgen-0.6.8_1 -> rust-cbindgen-0.7.1 sane-backends-1.0.27_4 -> sane-backends-1.0.27_5 sudo-1.8.27 -> sudo-1.8.27_1 thunderbird-60.4.0_2 -> thunderbird-60.5.0 tradcpp-0.5.2 -> tradcpp-0.5.3 wayland-1.16.0 -> wayland-1.16.0_1 webp-1.0.1_1 -> webp-1.0.2 zsh-5.6.2_1 -> zsh-5.7_1 -- You are receiving this mail because: You are on the CC list for the bug.
