[Bug 1728012] Re: Many 3rd party scanner drivers are broken by a sane change
I have a USB-connected brother printer/scanner MFC-7420, hooked up to a
desktop running xubuntu 18.04.1 The printer works but the scanner does
not. I have tried pretty much every heck posted here and elsewhere but
to no avail. Here's what I have done and the error messages I got.
Heads up: I wonder what's the significance on the discrepency in (3)
below?
-
0) To install the drivers I following the instruction (+FAQ) on
https://support.brother.com/g/b/downloa ... all=128
including brother-udev-rule-type1-1.0.2-0.all.deb. The printer works, but not
the scanner.
-
1) Xsane says
Failed to open device `brother2:bus2;dev5'
Invalid argument.
(sudo xsane gives the same error message). When I fire up simple-scan
(sudo or otherwise) it says
Ready to Scan
Brother MFC-7420
but when I click "scan" I got "Unable to connect to scanner".
-
2) scanimage -L
device `brother2:bus2;dev5' is a Brother MFC-7420 USB scanner
scanimage --test
scanimage: open of device brother2:bus2;dev5 failed: Invalid argument
-
3) lsusb
Bus 001 Device 002: ID 04f9:0180 Brother Industries, Ltd MFC-7420
[ Question: How come it says 001:002 when xsane complains about 002:005
?!! ]

[Question: According to
https://cromwell-intl.com/open-source/x ... ument.html
the command above should have listed "scanner" but as you can see it's not
there]
---
4) I have copied files from lib64 to lib, such as
sudo ln -sf /usr/lib64/libbrscandec*.so* /usr/lib
Reboot but to no avail.
---
5) I added myself to the scanner group:
sudo usermod -a -G scanner (me)
Reboot but to no avail. I also tried
more /etc/group | grep -n scanner
and here's the output:
59:scanner:x:120:saned,(me)
6) I edited /lib/udev/rules.d/60-libsane1.rules following the heck in (#12 of)
https://easylinuxtipsproject.blogspot.c ... nters.html
Reboot but to no avail.
7) There is no "brother.conf" in /etc/sane.d
8) I used synaptic to delete all "brother" related files, reinstall the drivers
in (step 0) above, reboot but to no avail.
9) I added the following two lines at the end of
/lib/udev/rules.d/40-libsane.rules (Before the line "# The following rule will
disable ...")
# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"
Reboot but to no avail.
I'm at a lost on what to do. The scanner (again, it's USB-based, not wireless)
worked until window, but I no longer have access to the window machine and I
really need the scanner for work. Your help and advice is most welcome. THANKS!

[Bug 1810009] [NEW] cannot install texlive fonts in 18.04
Public bug reported: I installed from scratch lubuntu 18.04.1 on my 32-bit netbook (previously running lubuntu 16.04). The installation went well and I was able to reboot the machines and installed other (non-tex-related) softwares. But when I tried to install texlive-latex I got massive errors. Eventually I tracked down the problem to a single package, fonts-lmodern. I used synaptic to purge all texlive related packages and then installed fonts-lmodern to isolate this one error message: W: Failed to fetch http://ftp.utexas.edu/ubuntu/pool/main/l/lmodern/fonts-lmodern_2.004.5-3_all.deb Connection failed [IP: 146.6.15.16 80] I posted this question in the "answers" sections of launchpad and eventually got help resolving this problem: https://answers.launchpad.net/ubuntu/+source/texlive- extra/+question/677188 Solution: edit /etc/apt/source.list by replacing all the http by https Note: (1) I ran into this problem with multiple texlive fonts; fonts- lmodern just happened to be the first one synaptic complained about. (2) These fonts packages (over 40 of them) are installed as part of texlive-latex-base; until I edited source.list as described above I was not able to install latex. Presumably that is an important tool for many people (certainly for me) so I report the bug (?) here, even though the answer section already resolves the issue. (3) I ran into this same issue in linux mint 19.1 xfce on a 64bit laptop. Mint's has a different repo setup and I have not yet figured out how to fix this. I also know that launchpad is not responsible for mint. I mention this solely to point out that (I believe) this is not a "32 bit issue".

[Bug 996791] Re: Xubuntu 12.04 extremely slow login
The patch in the OP worked for me (12.04.01, x64) until two days ago; after performing a regular system update the slooow login returned. I tried the fix in post #48 in this thread; it worked once (after I rm both directories) but no more (even after I tried to rm the directories again). I went back to the ubuntuforms link in the OP and the fix in post #40 there works (for now): After lightdm comes on, switch to tty1 and 'sudo pkill accounts'. This survives logout (so far) but not restart/reboot. I have sent along several logs in case this would help squash this veeery annoying bug. ** Attachment added: lightdm.log https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/996791/+attachment/3518071/+files/lightdm.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996791 Title: Xubuntu 12.04 extremely slow login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/996791/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 996791] Re: Xubuntu 12.04 extremely slow login
I just installed xbuntu on a new netbook (acer ao756) and I believe I run into this exact same problem: After I enter my password and hit return, it takes a long time to start xfce. I checked /var/log and found some strange error messages in three log files, all seeming related to lightdm. Note in particular log file #3, the warning at 36sec and at 86sec (and more to the point, the time gap preceeeding these two). I run xubuntu 12.04 on my desktop as well and I have never experience this delay between login and xfce starting. The desktop does have higher spec and to my surprise I have the same x-0-greeter.log error (log file #1) before, but lightdm on the desktop has no warning message (log file #3). All, this slow-login problem on the netbook happens often but not always -- 50-60% of the time? One more thing: the directory /usr/share/themes/Greybird-lightdm has a lot few files/folders than other themes (e.g. Default). I wonder if this is an xfce thing or it is a general lightdm problem (see log #1 for example). Other than this problem I really love this little netbook. Thanks for your help!
