I have a 16gb card in my laptop running Lubuntu 18.04, which is formatted as swap. when I click on activate partition in Disks I get this error:


while the partition is recognized as swap by the app


  • Did you ever run mkswap on that partition? – ubfan1 Nov 25 '18 at 21:09
  • do I do mkswap /dev/sdb1 – Stephen Nov 25 '18 at 22:13
  • That should use the whole partition, see the man page, man mkswap. – ubfan1 Nov 25 '18 at 22:33
  • if you know what should be done pls show it, otherwise you should not post anything. – Stephen Nov 25 '18 at 23:43
  • What you wrote is exactly the command, so "Yes" to your question. – ubfan1 Nov 25 '18 at 23:49
