Hi,
I have found a way to make it work right.
While zram was loaded, with one block device created only instead of two
as I have a dual-core, and with a priority 100 instead of 5 as the zram-
config brings I did this:
$ sudo swapoff /dev/zram0
$ sudo rmmod zram
then edited /etc/modprobe.d/blacklist.conf and added this:
blacklist zram
since the other day, I had no more zram loaded nor zram virtual device
loaded. Just now I thought of a test while zram is not loaded at boot
time:
$ sudo apt-get install zram-config
.......
.......
Réception de : 1 http://archive.ubuntu.com/ubuntu/ vivid-proposed/universe zram-config all 0.3.1 [4 266 B]
........
.......
$
$ sudo systemctl enable zram-config
$ sudo systemctl start zram-config
$
While I'm here: Could the zram-config script come with some outputs
there? Confirmation "we have created a symlink blabla... " and after,
"we have started zram-config successfully" ? That would be nice. :)
Result:
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/sda6 partition 4607996 0 -1
/dev/zram0 partition 947216 0 5
/dev/zram1 partition 947216 0 5
$
Now it works as it's supposed to!
Some more tests to be sure, with the systemctl commands "status", "restart", "start", and "stop":

They all show it works correctly.
Again, after "restart" "stop" and "start" some confirmation messages for
success would be nice.
One more: I'd like to have some direct mean to setup the size of the
block devices to my liking. A /etc/default/zram configuration file for
this purpose, for example, would be nice.
Best regards,
Mélodie

Title:
(Vivid) zram-config 0.3 Job for zram-config.service failed
Status in zram-config package in Ubuntu:
Fix Released
Status in zram-config source package in Vivid:
Fix Committed
Bug description:
[Impact]
* People using some non English locale, zram devices are not loaded
* The service fails to stop and unloading zram module as well
[Test Case]
* Install the new zram-config package
* Reboot and check that the zram devices are created:
$ swapon -s
-> returns some zram devices
* $ sudo systemctl status -l zram-config.service
-> no error
* Stop the service:
$ sudo systemctl stop zram-config.service
* $ sudo systemctl status -l zram-config.service
-> no error
* swapon -s
-> no more zram device listed
[Regression Potential]
* Services loading change may impact English-local user. However, the fix has already been confirmed to be working on wily.
* Stopping the service was already failing on unloading the module, so no additional regression is possible there.

Hi,
While testing how zram-config is going in Ubuntu Vivid, I meet with
error while doing restart and or stop/start.
It seems to stop fine but throws an error when starting again or
performing a restart.
I have installed zram-config 0.3 just today and haven't rebooted yet.
The CPU is "AMD Athlon(tm) II X2 260 Processor"
As stated in bug #1449665 there is one block device created:
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/zram0 partition 947216 0 5
$
Here:
$ sudo systemctl stop zram-config
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/zram0 partition 947216 0 5
$
after the stop, the prompt is back without error, but it has done
nothing.
With restart:
$ sudo systemctl restart zram-config
Job for zram-config.service failed. See "systemctl status zram-config.service" and "journalctl -xe" for details.
$
When invoking the suggested commands:
****

I have done a test using directly the scripts created for /usr/bin,
the results seem interesting:
$ sudo /usr/bin/end-zram-swapping

$ cat /proc/swaps

$
I hope I have tested the right way. If anything more is needed, log
files or so, please ask.
