Is it possible to add system wide rocker gesture for Ubuntu?
Rocker gesture is basically a following sequence of events :
ButtonPress event: mouse1
ButtonPress event: mouse3
ButtonRelease event: mouse3
This should trigger on focused window:
KeyPress event: XF86Forward
KeyRelease event: XF86Forward
And the reverse to get a XF86Backward event.
How can I add this functionality?
Totem used to have single window mode with playlist. This mode of operation has been removed in new versions so I'm looking for a simple media player with similar features.
Are there any media players with these features? I don't need any media library indexing or such, just a simple media player with playlist in single window.
When I change volume using the media keys there is a popping sound notification.
Sometimes I'm playing media, and I want to adjust the volume without sound notification.
I want to add Volume up, muted -> Shift + Audio raise volume shortcut.
How do I do it?
Binding Shift + Audio raise volume to amixer set Master 10%+ changes the volume, but doesn't display the visual indicator of volume change.
Looking at dbus-monitor shows different events:
Stock Volume up:
method call sender=:1.4 -> dest=:1.25 serial=2167 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=GetCapabilities
method return sender=:1.25 -> dest=:1.4 reply_serial=2167
array [
string "body"
string "body-markup"
string "icon-static"
string "image/svg+xml"
string "x-canonical-private-synchronous"
string "x-canonical-append"
string "x-canonical-private-icon-only"
string "x-canonical-truncation"
string "private-synchronous"
string "append"
string "private-icon-only"
string "truncation"
]
method call sender=:1.4 -> dest=:1.25 serial=2168 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=Notify
string "gnome-settings-daemon"
uint32 0
string "notification-audio-volume-medium"
string " "
string ""
array [
]
array [
dict entry(
string "x-canonical-private-synchronous"
variant string "volume"
)
dict entry(
string "value"
variant int32 61
)
]
int32 -1
method return sender=:1.25 -> dest=:1.4 reply_serial=2168
uint32 0
signal sender=:1.49 -> dest=(null destination) serial=1119 path=/com/canonical/indicator/sound/menu; interface=com.canonical.dbusmenu; member=ItemsPropertiesUpdated
array [
struct {
int32 3
array [
dict entry(
string "x-canonical-ido-volume-level"
variant double 61.5646
)
]
}
]
array [
]
Then amixer set Master 10%+:
signal sender=:1.49 -> dest=(null destination) serial=1116 path=/com/canonical/indicator/sound/menu; interface=com.canonical.dbusmenu; member=ItemsPropertiesUpdated
array [
struct {
int32 3
array [
dict entry(
string "x-canonical-ido-volume-level"
variant double 73.5641
)
]
}
]
array [
]
It seems that Volume up also runs some command that checks capabilities and shows a volume indicator. Where can I call this command directly?
I have a collection of images and an image that I want to generate from that collection.
What software is there available for Ubuntu for generating a mosaic image? How to do it?
My laptop has hardware switch for enabling and disabling wireless adapters. This includes both bluetooth and wlan. I rarely use bluetooth and would like to keep it disabled (soft blocked) unless I manually enable it. Is this possible?
rfkill list when HW-switch disabled:
1: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: yes
Hard blocked: yes
2: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: yes
HW-switch enabled:
1: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
7: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
This is what I would like to have when HW-switch is enabled:
1: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: yes
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
I have ThinkPad X61s with Ubuntu 11.04.
It seems that Ubuntu runs some script or command when I signal that I want to undock my laptop by pressing the undock button on the dock. Most visible thing that happens is that resolution on external display is changed.
After prepearing for undock my laptop is still connected to power, VGA-output and audio jacks through dock but not to any usb devices or optical drive. I'm running 11.04 on a ThinkPad X61s with X6 UltraBase.
What happens when I signal undocking?
This is what dmesg says after pressing undock button:

What software can I use to take screenshots with a set interval? I'd like to take screenshots every 2 second or so. Command-line and GUI are both ok.
I'd prefer software that can also resize and compress each screenshot.
I need to convert a video file from Matroska container into mp4 container. Matroska file contains one h.264 video track and one AC3 sound track. It should be possible to do this losslessly, but how to do it with native Ubuntu tools?
Transcoding is not an option.
I have a webcam that works as a v4l2 device.
What is the most convenient way to capture either a stop-motion or time-lapse video?
N.B.
stop-motion and time-lapse are related but conceptually different.
Time-lapse is where you take a photo of a scene at a set interval and then combine it into a video (that looks like it's going really fast).
Stop-motion is where you control the scene and take an image for every change you make, to form an animation (eg Wallace and Grommit).
An application for time-lapse needs to be able to take a photo at a set interval.
