After resuming my computer from suspend/restarting it the sound output is allways changed to another sound output device in list found in the sound settings after the upgrade to Ubuntu 17.10. To be able to use the mute/volume up/volume down keys I have to change the output device every single time I resume the computer.
Is there a solution/workaround for this?
After updating from Ubuntu 17.04 to 17.10 hibernate after suspend (hybrid suspend) stopped working. Since switching to systemd I used this solution https://wiki.debian.org/SystemdSuspendSedation (after the solution with a script in /etc/pm/sleep.d also stopped working) but now my computer only enters suspend mode and stays there forever.
systemctl hibernate is working and I don't have a clue why it's not working any more.
How do I make hibernate after suspend working again?
Additional information: I'm using the tuxonice kernel.
edit:
What I recently found out is that systemctl suspend and sudo pm-suspend seem to do different things in Ubuntu 17.10, as when I use sudo pm-suspend the old script in /etc/pm/sleep.d works as intended but the systemd style script still does nothing.
I installed tuxonice in Ubuntu 13.10 and everything works as intended (resuming, hibernation). The only strange thing that happens is that it get a "Resuming from /dev/disk/by-uuid/..." message when I just boot up my computer that I usually only get when my computer really resumes from hibernation. The only diffrence between the two situations is that on a normal boot the dots on the splash animation change and on resuming are just static white.
How can I remove the unneeded "Resuming..." message on a normal boot?
In a script I want to open a window which is missing the "close" button in the title bar, so that it can't be accidentally be closed, but still has the "minimize" and "maximize" buttons.
Is this possible? Maybe via some window manager arguments?
I'm using Ubuntu 13.04 with Unity.
I tested CPU frequencies with either the Intel tool i7z and turbostat from the linux-tools package (sudo modprobe msr, sudo turbostat) and what I find as maximum frequencies for two different processors is lower as what Intel states as maximum turbo frequency.
I tested with MrBayes MPI on 4 cores with governors ondemand and performance and the 'turbo' option using indicator-cpufreq.
i5-3210M - Intel specifications max. freq.: 2,5GHz - 3,1GHz Turbo
max. measured: 2,89GHz
i5-3470 - Intel specifications: 3,2GHz - 3,6GHz Turbo
max. measured:3,39GHz
I also tried for i in {1..4}; do burnK7 & done in tty1 and turbostat in tty2 and got the same results.
Why are the max. Turbo CPU frequency I can measure running Ubuntu lower than the ones Intel states? Where are the "missing" 0,21GHz?
I use my trackpad with touchegg and touchegg-gce for easier configuration. In the initial configuration there's an 'application' section for Chromium navigation which uses 2-finger drag that doesn't seem to work in Chromium or in Firefox (when I add Firefox).
The problem seems to be that the 2-finger drag is used for scrolling left and right. I have the feeling that an override for this function in Chromium or Firefox doesn't work and scrolling is "more important" than forward or back navigation.
With an iMac I saw that this is possible so did anyone get the trackpad to be usable for browser navigation?
On my dual boot laptop I noticed that maximum brightness in Ubuntu and Windows 8 is totally different. In Windows 8 the screen is much much brighter at maximum level than it is at Ubuntu maximum level. (I was even asked why my laptop display looks that dim.)
I have a Lenovo ThinkPad E330 Laptop with Intel HD 4000 graphics.
How can I increase the maximum brightness level Ubuntu uses?
I'm on Ubuntu 12.10 and dual boot. I have put the Windows partitions to the launcher blacklist so that they won't show up there (via "unlock from launcher" option). These partitions will then appear in the blacklist viewable in dconf-editor. But when I start gparted all blacklisted partitions reappear in the launcher ( and get lost in the blacklist as well).
Is this intended or a bug (I would guess it's a gparted bug, as I don't get the result when I start gnome-disks)? Does anyone know how to solve this?
When I open an application as root I get gnome2-like scrollbars which is fine.
But:
Is there any way to resolve these issues? Can't they look like in Firefox for example?
Often my laptop is just standing around and just playing music and for the below mentioned actions I don't need to see wat's going on on my desktop.
Is it possible to use the volume and playback keys (no fn keys) of my keyboard to use
without waking the monitor/display of the laptop?
Out of a sudden after I logging in to the 'Ubuntu' session Unity or maybe Compiz doesn't start anymore (actually I'm not sure wether it is Compiz or Unity). I can start Unity manually with setsid unity & and put the command as a startup script but that's not how it should be.
I also tried a lot of "solutions" but none of them helped:
The question now is, how do I get Compiz/Unity to be started propperly at login again?
I'm on 12.10 with Intel graphics.
Everytime I start Dropbox (in Precise) it gets added to the autostart list even if I deleted the entry before. I don't want Dropbox to be started when I log in only when I want it to. How to prevent Dropbox to be automatically added to the autostart list?
When I resume my laptop and had radiotray turned on it starts playing again (from buffer) while I'm on the lock screen. This gets really annoying when I'm somewhere it should be quiet (library, train etc.). It would also be nice to have some delay in resuming radiotray playback after unlocking the screen to be able to react to the situation I'm in.
How do I prevent that behaviour (ok, besides turning radiotray off before suspending)?
When I start some applications like Gimp or update-manager they start like if they where maximized but they have window decorations, are not integrated into the Unity panel and therefore move towards the screen bottom. I also tried to force maximize behaviour via compizconfig-settings-manager but that doesn't change anything.
What can I do to start these applications maximized with integration into the Unity panel?
On my laptop using 12.04 I would like to have two virtual desktops, one should be visable only to the person using the computer and the other should be the one that is shown when I attach an external device. At the moment I use the "mirror display" (not sure about the english name for it) functionallity or the "not mirror display" option, but with different virtual desktops it would be nice to set up the "external monitor" before and afterwards look at some notes while giving talks etc.
How can I ajust the settings to achieve this?
Saw a lot of old questions, but no real solution. Maybe this got better with Precise multi-monitor support.
I use Ubuntu One together with the indicator for the panel on two differnt laptops (installed the same way). On one laptop Ubuntu One connection is started automatically after login where on the other it isn't.
How can I get the behaviour of Ubuntu One not being connected automatically after login?
I noticed that the Sushi (gnome-sushi) previewer uses around 60MB of RAM and wondered why it has to be so much memory, as I can only preview a single image/sound file at a time?
eog (eye-of-gnome) the default picture viewer uses around 30MB and deadbeef a lightweight music player around 10MB RAM and they aren't that much slower in showing up.
When I'm logging in to Unity in 11.10 it takes about 15-20 seconds for the Desktop to be ready. When I compare that to the loading times of 10.04 where it's almost instant there is a huge discrapancy in log in times. Is gnome3/Unity really that massive to not be loaded faster?
Please no unnecessary comments about:
autostart applications as I set none (at least not by autostart option via cog).
bootup-manager as I reduced the processes there to a minimum
In Oneiric shutdown is a lot slower than in previous releases and when I look at the console text while shutting down there seems to be a problem with the network manager. Now I wanted to know how I log the text being shown during shutdown.
