• Apport-gpu-error-intel.py crash

  - by artfulrobot

  Feeling disempowered by Ubuntu's new bug reporting policy/system. My Intel i5 machines have all experienced daily (if not more frequent) freezes, but it's very difficult to report bugs now and policy instead is just for ubuntu to collect counts; no way for me to see that anything is (or is not) being worked on. I've just experienced a freeze and now on reboot I'm stuck in a cycle of "Ubuntu has an internal error" (presumably Ubuntu never experiences an external error...) do you want to report it? Yes. Oh another internal error... It looks like this report could contain useful information. Is there anyway to make sure it gets provided to the people who can fix it?

• Keyboard problems on Acer Laptop

  - by artfulrobot

  The key map on my Acer Aspire 5750 keyboard has gone awry since I had the keyboard replaced (because of physical fault with one of the keys). The new keyboard looks identical, but now Ubuntu seems a little confused about which (function) buttons are which. So previously Fn+left/right were, as marked on the keys, brightness up and down; Fn+up/down were volume. It all worked as advertised! But now Page Dn (which is marked as Page Dn or Back a track with Fn) is turning the volume up, and the others fn+arrow keys don't work at all. Is there a way I can see what's happening or get it to re-map my keys? Thanks.

• How do I control remote Windows 7 machine? VNC/RDP/?

  - by artfulrobot

  I have a Windows 7 laptop that's going out and about and I'd like to be able to admin' it from my Ubuntu (precise) desktop. While the laptop is in my office I can use Gnome's "Remote Desktop Viewer" (Vinagre) to connect via RDP. However, when it's in the office I don't really need RDP of course! And when it's out of the office I cannot control the routers/firewalls along the way, so I won't know the IP and cannot set up port forwards. I'm looking for a Ubuntu compatible way to achieve this. Nb. I can set up port forwards at the my office end, so a service on the laptop could try a "backwards" connection to my client.

• Can I install new version of Ubuntu in spair RAIDed partition with unetbootin

  - by artfulrobot

  I have Ubuntu 11.04 running on my home desktop which has 2 hard drives mirrored by RAID. The drives are partitioned with a big data partition, a swap partition and a couple of 20Gb partitions for OSes, one is 11.04 which is in use, and the other is kept spare for installing a later version. Which is what I'd like to do now. The idea of a 2nd partition for new OS is that I can try it, and if it's problematic, I can boot back into the original one - the machine is shared with others, so I need it to stay available! I have had horrible problems with software RAID after using a Live USB stick - basically it messes up the internal numbering of the RAID drives or something, anyway, the result is you can't boot after using it :-( and have to spend ages re-assembling the arrays, trying to remember grub commands etc etc. Quite a shocker when you consider booting from a Live USB is supposed not to affect the existing system. As I'm installing in a RAIDed disc, I would typically use the Alternative install (sad to hear that this is going to be dropped in future). However, I think I might be able to use unetbootin to trick the system into working on top of the existing system that understands RAID, with the normal ISO? If unetbootin loads from drives that are already understood to be RAIDED, then presumably it will only see md0... instead of sda, sdb... and as long as I don't need to repartition (I don't) it should be fine, right? Or is that just plain foolishness? Please tell me before I end up with a dead system (again!)

• How do I stop Ubuntu Precise freezing/hanging

  - by artfulrobot

  At least once a day I lose work on my (2 different) Intel i5 machines running Ubuntu 12.04. The entire system will freeze/lock-up/hang, and never return. At this point nothing works; even the caps lock key doesn't toggle the light on the keyboard; Ctrl-Alt-F1 won't do anything either. askubuntu.com is apparently where I'm directed for support. I suspect this is a kernel bug. But I simply can't keep losing work like this, so I'm anxious to try whatever it takes to get the thing reliably working. Can you suggest something I can try to fix the problem an existing bug I can follow progress on and contribute to (from users/tester's POV) the most constructive way I can contribute to helping fix the problem, keeping in mind that I do need the computer (so can't do things that might "brick" it!)

• How do I disable window move with alt + left mouse button in GNOME Shell?

  - by artfulrobot

  There are lots of posts on this about Unity, this is about gnome-shell As with other posters, I use apps (Inkscape in particular) that uses Alt-Click and Alt-drag. Gnome-shell is grabbing this off me and thus disabling features in the application. I have tried using ccsm's Move plugin - you can turn this off and you still get Alt-drag window moving. using gconf editor to change /apps/metacity/general/mouse_button_modifier - this has no effect AFAICS. It's really hindering me. Otherwise I find gnome-shell a really productive environment.

• How to add a printer in gnome-shell

  - by artfulrobot

  I'm using Gnome Shell (although I'm not sure whether the "Printers" app is part of that or just part of Gnome). I go to "Printers" from the overview, click the + button on the bottom left, choose network and then see a message "FirewallD is not running. Network printer detection needs services mdns, ipp, ipp-client and samba-client enabled on firewall.". It's not auto detected anything. There's an Address box and a Search by Address tickbox, but neither seem to do anything. I'm frustrated because I know all the details of the printer, but have nowhere to put them in. Automation is supposed to make things easier, no? For example I know the printer is at lpd://10.67.5.3/lp1 but I can't put this in anywhere. Is there a GUI that works, or have I misunderstood how to use it?

• App for finding icons easily?

  - by artfulrobot

  Occasionally I need to use a custom icon for something - a launcher created with alacarte, a custom .desktop file, or just a particular folder viewed in Nautilus. I know there are LOADS of cool icons installed on my system at /usr/share/icons but browsing them is really awkward. Everything is scattered around, duplicated in different sizes (or symlinked to .svg) etc. So, say I'm looking for a text file icon, or a purple folder or such, searching is a faff, and then when you do find results you need to work out what the best quality one is. Made me think that someone might have written an app for this?

• Cannot access Windows 7 share from Windows XP

  - by artfulrobot

  I have a new Windows 7 machine named PAP44 in the PAP workgroup. The networking is set to "Work" mode for the wired LAN. I have a couple of users and I've shared a folder and set it so both users can read/write. Confusingly for me, rather than sharing just that folder (as I'm used to with older versions of Windows) it appears to be sharing a path (\\pap44\users\...\myFolder) From another machine on the LAN, running XP, when I go to \\PAP44\Users I'm asked for a username and password, but neither of the usernames+passwords work. It just jumps back to the username and password dialogue, except that the username I entered gets prefixed with PAP44\ My end goal is to get my Debian/Ubuntu machines to be able to access this share, but first of all I thought I'd try to get it working in Windows, after all, that's supposed to be easy! Is there another step? (PS. I am not a "hit and run" case!)

• exim greylisting non-auth SMTP mail?

  - by artfulrobot

  I have smtp auth set up on my exim4 Dqueeze server so that only auth'ed clients can use it as a mail relay. I believe this is working, e.g. thunderbird (w/out password) reports that I am "not yet authorised to send mail for X from Y". I also have greylistd installed, which I also see to be working. But I've noticed that when an unauthorised connection is made the error is temporarily rejected RCPT <[email protected]>: greylisted Should greylisting be taking effect here? Surely it should just be saying "go away, you're not authorised" rather than filling up a greylist queue?

• Debian date jumping, causing complete lockup

  - by artfulrobot

  I have a Debian Squeeze VM that has suddenly chosen to jump it's date forwards just over a month, which seems to confuse it no end and cause it to require a hard reset (yikes!). There is nothing unusual in the logs, except that the datestamp suddenly jumps (today back to 2005). It's happened three times, so I don't think it's to do with the leap second issue as the last one of those was in July. When it happened once I spent ages checking stuff but could not find anything, decided to forget it. But three times is becoming an issue on a production server. Edits providing information requested in comments (thanks!): I do not have control over the hypervisor, it is a hired VM. # cat /sys/devices/system/clocksource/clocksource0/current_clocksource kvm-clock # ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== +grendel.exizten 130.149.17.8 2 u 29 64 77 14.811 1.778 1.744 *panoramix.linoc 193.67.79.202 2 u 32 64 77 19.729 -0.419 1.691 +robert.elnounch 213.251.128.249 2 u 27 64 77 17.762 0.600 1.722 -janetzki.eu 83.169.43.165 3 u 31 64 77 27.214 3.575 1.638

• Wifi channel interference

  - by artfulrobot

  In my neighbourhood there are: 11 wifi signals on channel 1 2 wifi signals on channel 4 (including mine at the mo) 8 on channel 6 6 on channel 11 According to the diagram on wikipedia Mine on channel 4 will suffer interference from channel 1 and channel 6, so a total of 20 other networks(!). So would I be better to join channel 11, even though my network is then in direct competition with the 6 others? I suppose the question is: what's worse: direct interference (meaning that on the same channel) from 6 or fringe interference from many more networks?
