I made a dkms package that fixed the problem for 19.04 (check above).
By the way. I went to linux kernel 5.2.1 ideapad_laptop.c and now there's no no_hw_rfkill_list. It's the opposite, now it has to be specified if there is a hw-rfkill. So that new laptops don't get this problem. One option is to install a ppa with a recent kernel. >From the file: * Some ideapads have a hardware rfkill switch, but most do not have one. * Reading VPCCMD_R_RF always results in 0 on models without a hardware rfkill, * switch causing ideapad_laptop to wrongly report all radios as hw-blocked. * There used to be a long list of DMI ids for models without a hw rfkill * switch here, but that resulted in playing whack a mole. * More importantly wrongly reporting the wifi radio as hw-blocked, results in * non working wifi. Whereas not reporting it hw-blocked, when it actually is * hw-blocked results in an empty SSID list, which is a much more benign * failure mode. * So the default now is the much safer option of assuming there is no * hardware rfkill switch. This default also actually matches most hardware, * since having a hw rfkill switch is quite rare on modern hardware, so this * also leads to a much shorter list. */ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1837136 Title: ideapad_laptop disables WiFi/BT radios on Lenovo Y540 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1837136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
