Issue 538 in xmonad: X.H.DynamicBars call to xrrSelectInput has no effect
Status: New Owner: ---- New issue 538 by johnnysp...@gmail.com: X.H.DynamicBars call to xrrSelectInput has no effect http://code.google.com/p/xmonad/issues/detail?id=538 What steps will reproduce the problem? 1. Use attached xmonad.hs (vanilla + minimal DynamicBars). 2. Turn second display off and on: xrandr --output VGA1 --off xrandr --output VGA1 --preferred --right-of LVDS1 Bonus: 3. Apply select_input_fix.dpatch, rebuild and restart xmonad. 4. Turn second display off and on. 5. Undo previous patch, apply select_input_not_fix.dpatch, rebuild and restart xmonad. 6. Turn second display off and on. What is the expected output? What do you see instead? Expected: In steps 2, 4, and 6: see "DESTROYING"/"CREATING" messages in xmonad output. Actual: Only step 4 produces the expected messages. Steps 2 and 6 produce no output. What version of the product are you using? On what operating system? xmonad 0.11 (darcs) xmonad-contrib 0.11 (darcs) xorg 1.14.0 xrandr 1.4.0 X11 (Haskell binding) 1.6.1.1 Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". "xmonad --recompile" produces no output. Please provide any additional information below. I'm expecting step 2 to work because dynStatusBarStartup calls xrrSelectInput. This apparently doesn't do what it's supposed to do for me, possibly for the same reason that step 6 doesn't work.

Comment #1 on issue 538 by MathStuf@gmail.com: X.H.DynamicBars call to xrrSelectInput has no effect https://code.google.com/p/xmonad/issues/detail?id=538 Finally getting back to this. I'm running with: ghc-xmonad-contrib-devel-0.11.2-5.fc22.x86_64 xmonad-core-0.11-12.fc21.x86_64 ghc-X11-1.6.1.1-5.fc22.x86_64 xorg-x11-server-Xorg-1.16.1-1.fc22.x86_64 % xrandr --version xrandr program version 1.4.3 Server reports RandR version 1.4 and I can't reproduce the first 1./2. step failure: ``` % pgrep -c xmobar 2 % xrandr --output HDMI3 --primary --mode 1920x1080 --output HDMI1 --off % pgrep -c xmobar 1 % xrandr --output HDMI3 --primary --mode 1920x1080 --output HDMI1 --left-of HDMI3 --mode 1440x900 % pgrep -c xmobar 2 ``` Can you still reproduce this? -- You received this message because this project is configured to send all issue notifications to this address.

Comment #2 on issue 538 by johnnysp...@gmail.com: X.H.DynamicBars call to xrrSelectInput has no effect https://code.google.com/p/xmonad/issues/detail?id=538 I have roughly the same versions as you (slightly newer where different): xmonad-contrib-0.11.3-1 xmonad-0.11-9 haskell-x11-1.6.1.2-1 xorg-server-1.16.2-1 xrandr program version 1.4.3 Server reports RandR version 1.4 I can still reproduce this: 1. Run xmonad with the attached xmonad.hs. Two xmobars are started, so barCreator works. 2. Kill the xmobars. 3. Toggle the external display off and on. No new xmobars are spawned, so barCreator isn't being called. In other words: ``` $ pgrep -c xmobar 2 $ killall xmobar $ pgrep -c xmobar 0 $ xrandr --output HDMI1 --off $ pgrep -c xmobar 0 $ xrandr --output HDMI1 --preferred --right-of LVDS1 $ pgrep -c xmobar 0 ``` Any suggestions for what to try next? Is there something that I overlooked in the attached minimal xmonad.hs? -- You received this message because this project is configured to send all issue notifications to this address.

Comment #3 on issue 538 by allber...@gmail.com: X.H.DynamicBars call to xrrSelectInput has no effect https://code.google.com/p/xmonad/issues/detail?id=538 MathStuf, your xorg is buggy. Selecting input only applies to the current connection; you create a new connection, select on it, and immediately close it, which in a non-buggy xorg has no net effect. -- You received this message because this project is configured to send all issue notifications to this address.

Comment #4 on issue 538 by aka....@gmail.com: X.H.DynamicBars call to xrrSelectInput has no effect https://code.google.com/p/xmonad/issues/detail?id=538 This problem was due to DynamicBars not receiving the randr events because it opened its own connection instead of asking XConf, so DynamicBars was buggy all along. A hypothesis on IRC was that it used to rely on a bug in Xorg that went away, which exposed the bug. Fix attached, credit geekosaur.
