Trouble to recognize external monitors at startup












5















I don't consider myself a linux guru. I'm not sure about what information I need to provide. I will gladly update my question if you give me the instructions.



Setup



HP Spectre x360 - 13-4190nz with Ubuntu 18.10



Office

laptop resolution: 2560x1440

second monitor: mini-display to hdmi, 2560x1440 primary

third monitor: hdmi 2560x1440



Home

laptop resolution: 2560x1440

second monitor: mini-display to hdmi, 1920x1080 primary

third monitor: hdmi 1920x1080



Note: I'm not entirely sure if my setup at home is exactly correct. I won't be home before a few days.



Detail of the problem



Whenever it's at home nor at the office, once I pass the login screen, Ubuntu detects only one of my external monitors and the screen is "unstable". The screen starts and stops like it has a bad contact or is badly connected. Once I open the Display Arrangement and change something, it fixes until the next reboot.

  • Could you post the contents of ~/.config/monitors.xml as well and then leave a comment @Fabby?

  • @Fabby I have updated with monitors.xml

  • Apparently Canonical updated the monitors.xml to Version 2, so I'm not really helpful here...

  • I think the problem is at home the second monitor is 1920x1080 and at work the second monitor is 2560x1440. Ubuntu is remembering the settings from last location and switching to new location is causing confusion. My instinct would be to setup two scripts: one for booting at home and one for booting at work. Haven't given it much thought though...

  • Could you post the contents of ~/.config/monitors.xml as well and then leave a comment @Fabby?

  • @Fabby I have updated with monitors.xml

  • Apparently Canonical updated the monitors.xml to Version 2, so I'm not really helpful here...

  • I think the problem is at home the second monitor is 1920x1080 and at work the second monitor is 2560x1440. Ubuntu is remembering the settings from last location and switching to new location is causing confusion. My instinct would be to setup two scripts: one for booting at home and one for booting at work. Haven't given it much thought though...

I don't consider myself a linux guru. I'm not sure about what information I need to provide. I will gladly update my question if you give me the instructions.



Setup



HP Spectre x360 - 13-4190nz with Ubuntu 18.10



Office

laptop resolution: 2560x1440

second monitor: mini-display to hdmi, 2560x1440 primary

third monitor: hdmi 2560x1440



Home

laptop resolution: 2560x1440

second monitor: mini-display to hdmi, 1920x1080 primary

third monitor: hdmi 1920x1080



Note: I'm not entirely sure if my setup at home is exactly correct. I won't be home before a few days.



Detail of the problem



Whenever it's at home nor at the office, once I pass the login screen, Ubuntu detects only one of my external monitors and the screen is "unstable". The screen starts and stops like it has a bad contact or is badly connected. Once I open the Display Arrangement and change something, it fixes until the next reboot.

I don't consider myself a linux guru. I'm not sure about what information I need to provide. I will gladly update my question if you give me the instructions.



Setup



HP Spectre x360 - 13-4190nz with Ubuntu 18.10



Office

laptop resolution: 2560x1440

second monitor: mini-display to hdmi, 2560x1440 primary

third monitor: hdmi 2560x1440



Home

laptop resolution: 2560x1440

second monitor: mini-display to hdmi, 1920x1080 primary

third monitor: hdmi 1920x1080



Note: I'm not entirely sure if my setup at home is exactly correct. I won't be home before a few days.



Detail of the problem



Whenever it's at home nor at the office, once I pass the login screen, Ubuntu detects only one of my external monitors and the screen is "unstable". The screen starts and stops like it has a bad contact or is badly connected. Once I open the Display Arrangement and change something, it fixes until the next reboot.

  • I think the problem is at home the second monitor is 1920x1080 and at work the second monitor is 2560x1440. Ubuntu is remembering the settings from last location and switching to new location is causing confusion. My instinct would be to setup two scripts: one for booting at home and one for booting at work. Haven't given it much thought though...

I think the problem is at home the second monitor is 1920x1080 and at work the second monitor is 2560x1440. Ubuntu is remembering the settings from last location and switching to new location is causing confusion. My instinct would be to setup two scripts: one for booting at home and one for booting at work. Haven't given it much thought though...

flock() on closed filehandle LOCK_FILE at /usr/bin/apt-mirror

Image
0 I recently upgraded an Ubuntu 16.04 virtual machine to 18.04. I regularly use this VM to run apt-mirror at school on their high-speed internet, then rsync these files to my rack-mount server at home for updating multiple computers at home without wasting the tiny amount of bandwidth I have there. Since updating I can't get apt-mirror to run on my VM. It keeps giving the error: flock() on closed filehandle LOCK_FILE at /usr/bin/apt-mirror line 214 immediately followed by: apt-mirror is already running, exiting at /usr/bin/apt-mirror line 217 apt-mirror is NOT running, and does not have a cron job. I've tried rebooting, and even looked for the old-style lockfile to delete, but I guess that method is no longer used. Is there some way to force unlock this so I can run apt-mirror? UPDATE: So...
