1 == Precise desktop paper cuts ==
5 # The indicator icon for configuring the display resolution no longer exists
8 * probably "by design", but... wtf
10 # When the control panel is open but --hidden behind other windows or-- on a different virtual desktop, clicking on "Sound Settings" or "Bluetooth Settings" does not bring it to the foreground, thus confusing users.
12 * confirmed on precise
14 # --Why can't the desktop remember that I don't want mirrored displays when I connect my laptop to the docking station?--
15 * this bug actually can't be reproduced every time I plug in an external monitor. It's hard to tell if there's an underlying logic.
16 * FIXED in precise or maybe in quantal
18 # It looks like the HDMI audio output remains selected even when the output gets unplugged. As a result, the laptop does not play sound any more.
19 You can fix the problem by going to Sound Settings and click once on the internal audio output (which is the only output).
21 # oneiric regression: Sometimes when I switch on the HDMI output, the sound also switches to it, but not consistently.
23 # oneiric regression: We've lost the workspace previews in the panel. There's indicator-workspaces on Launchpad ([[https://launchpad.net/~geod/+archive/ppa-geod]]), but it only shows the current desktop number.
25 # --oneiric regression: The System Load indicator doesn't start automatically on login--
27 # --oneiric regression: Tray icons, including the bluetooth icon and the KTorrent icon, sometimes disappears from the panel. The icons can still be seen by opening the unity-2d-panel.--
30 # --menus of GTK3 applications appear in the window itself rather than in the Unity panel--
34 # Displays: sometimes clicking on the second monitor does not select it. After fiddling with it long enough (dragging, clicking, etc) eventually it gets selected.
36 === Window management ===
38 # --Dragging windows around becomes slow and jerky after some time. OpenGL acceleration works fine, it seems like a compiz issue with the intel driver. I can easily reprodiuce this on a Thinkpad X201 (Arrandale), but it's a lot harder to trigger on a X220 (Sandybridge).--
40 * [[https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/770160]]: windows start to move slow after using compiz for some hours
41 * [[https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/773861]]: Moving windows is very laggy with Compiz
42 * [[https://bugs.launchpad.net/ubuntu/+source/unity/+bug/803943]]: compiz consuming a lot of cpu
43 * [[https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/888039]]: Gradual degradation in desktop performance.
44 * [[https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/891744]]: Dragging windows stutter during and after grid animation
45 * Improved in Precise, but there's still high cpu usage in some cases (see bugs)
46 * FIXED in Quantal and maybe also in Precise
48 # --When switching workspaces, focus can go to a window hidden behind another full-screen window. Compiz does not seem to remember which window previously had focus in each workspace.--
52 # When the video mode changes, full-screen windows get shuffled to different workspaces and don't come back to their original locations when the resolution changes back. This is particularly annoying when plugging/unplugging monitors.
53 * this is a longstanding issue with compiz
54 * confirmed on Precise
56 # the "Desktop Cube" plugin of Compiz makes the display flicker briefly every time I switch workspace. This happens both with a Thinkpad X201 (Arrandale) and X200s (GM45).
58 * confirmed on precise
60 # --If I drag an icon around in Nautilus, I can often make Compiz hang after a while. Restarting Unity from the console often cures the problem.--
63 # While dragging icons or other objects, I can only switch workspaces by going to the left edge. It doesn't work on the right. This happens with both "Desktop Wall" and "Desktop Cube".
64 * In precise, desktop switching works on both edges, but the screen flickers awfully
66 # You can't abort icon dragging with the ESC key
68 * Confirmed on Precise
70 # When dragging a window across the edge to another desktop, the mouse cursor jumps to the left or to the right, outside of the window title.--
71 * Confirmed on Precise
73 === Session management ===
75 # There's no longer a way to save the X session? Before it was working only for some applications, but it was still a big time saver after a reboot.
77 * confirmed on precise
79 # --Switch User Account locks my current session and then doesn't bring up the login screen. (I'm running gdm, not lightdm)--
85 # --The search bar often takes several seconds to show up when invoked with the keyboard--
89 # --There's a dead "Workspace Switcher" icon on the dock that doesn't do anything when I click on it and I cannot even remove it from the dock--
90 * It turns out that this icon works only if you enable Expo in compiz. Ok, but why can't I get rid of it??
91 * https://bugs.launchpad.net/ubuntu/+source/unity/+bug/921271
93 # --There's a trashcan icon on my dock that brings up a new tab in browser--
96 # --Notification OSDs won't go away by clicking on them. They just become more transparent when hovering the mouse. I can reproduce it every time by typing "notify-send foo" in a terminal--
98 * confirmed in precise
99 * NOTABUG: works this way by design :-(
100 * Workaround: uninstall notify-osd and install notification-daemon
102 # --I can't configure the key to switch focus to the launcher to Super alone. I had to resort to Super-space, which is not comfortable for me--
105 # --If I edit preferences in ccsm, sometimes Unity does not pick them up until restarted--
106 * I haven't seen this in a while, it's probably fixed
108 # When I enable or disable a plugin in ccsm, sometimes compiz hangs. If I kill it, it takes down the whole X server
109 * See: http://people.sugarlabs.org/bernie/Xorg-crashed-on-compiz-close.0.log
110 * Confirmed on Precise
114 # --The Gnome Control Center (aka System Settings) often closes when clicking on icons. I suspect it's simply crashing.--
118 # --Evolution 3: the (webkit based) mail preview pane sometimes "crashes". It remains blank or garbled and there's no way to restore it until I restart the application.--
121 # --Evolution 3: forgets my Google account password every time I start it. Works with other IMAP accounts.--
124 # --Evolution 3: my Google calendars no longer show up (no errors are displayed). The CalDAV calendars still work.--
127 # --Evolution 3: sometimes Evolution just stops polling for email until I restart it--
130 # Evolution 3: sometimes Evolution hangs on shutdown until I kill it from the terminal
132 # --Evolution 3: this might sound like a rant, but due to many other stability issues with Evolution, my email experience has become really miserable in Oneiric.--
136 === Hardware support ===
138 # When I connect a monitor to the DisplayPort output, sometimes the sound output also switches to it (but sometimes it doesn't, I couldn't figure out why). The sound output setting is buried deep into Control Panel / Sound Settings / Hardware / Profile, so it took me a while to figure out what had happened the first time.
141 # HDMI/DisplayPort sound no longer works
142 * Probably this kernel 3.2 regression: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/973704
143 * Fixed in upstream kernel 3.4
145 # If I unplug AC while the lid is closed, the laptop does not automatically suspend. This is very dangerous because you can accidentally store your laptop in a backpack while it's still running.
146 * https://bugs.launchpad.net/ubuntu/+source/linux/+bug/886629
148 # --Wifi becomes incredibly slow after a few minutes of use (like, 1-2kb/s). This is a an Intel iwlagn 6250. I tried all kernels all the way to 3.2 with no improvement. The only workaround I could find is disabling 802.11n support.--
149 * Likely this bug: http://marc.info/?l=linux-kernel&m=131914553920614&w=2
152 # --My jWin Bluetooth headphones stop working when there's no sound output for about 30 seconds. After this, all applications that try to play some sound will hang until I disconnect the bluetooth device--
153 * Fixed in kernel 3.2
155 # The Bluetooth headphones don't get automatically reconnected when I turn them on. Clicking on Connect in the control panel seems to work for one second, then it fails. The only way to reconnect is removing the device and then paring it again.
156 * https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/437649
157 * confirmed on precise
159 # --Sometimes, when switching monitors on/off, the DisplayPort output starts to flicker. Looks very much like a double-buffering issue--
160 * I've not seen this in a while, maybe fixed
162 === Upgrade issues ===
164 # --After upgrading to Oneiric, the machine became unbootable due to an incomplete /run migration. There's a bug in Launchpad, but it's not getting any attention.--
166 * Maybe fixed in Precise
168 # My home is dm-crypt encrypted, alghough not with luks. After upgrading to Oneiric, it was no longer being mounted because mount thought it was of type minixfs. WTF?? To fix this, I had to pass '-n nominix' to blkid in /lib/cryptsetup/checks/un_blkid. This filtering was present in an earlier version of cryptsetup, but it has been removed in 2:1.1.3-1.
171 # --On my x200s, something goes wrong when initramfs tries to switch to the root filesystem. Due to a race with udev, some files cannot be deleted in the tmpfs--
173 * https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/155689
174 * https://bugs.launchpad.net/ubuntu/+source/linux/+bug/613273
175 * FIXED: incomplete /run migration
177 # Apport no longer starts when something crashes in my unity session. It works for newly created users.
179 # --Tool tips have become black on black (hence, unreadable)--
180 * Confirmed on Precise
181 * https://bugs.launchpad.net/ubuntu/+source/gtk2-engines/+bug/144968
182 * I fixed this myself by editing sutff in dconf, but... wtf ubuntu!
