I also have a system which I thought could not be upgraded beyond 12.04 because of a lack of PAE support, but then I recently found that many Pentium M CPUs can work with a PAE kernel, but do not advertise PAE support.
To check whether this is the case for your system, simply install a PAE kernel: sudo apt-get install linux-generic-pae linux-headers-generic-pae See: https://help.ubuntu.com/community/EnablingPAE If you find your system really does not work with a PAE kernel, all is not lost, see: https://help.ubuntu.com/community/Lubuntu-fake-PAE I'm marking this bug as affecting modemmanager instead of modem-manager- gui. ** Changed in: modem-manager-gui (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1340154 Title: On modem initialization, Modem Manager 0.5.2 sets text mode instead of PDU mode for SMS, but newer modems can't work in this mode Status in “modem-manager-gui” package in Ubuntu: Invalid Status in “modemmanager” package in Ubuntu: New Bug description: To-date, cannot utilise Modem Manager GUI in 12.04 LTS, as it is understood that there is a 'bug' in Modem Manager version 0.5.2 that installed in Ubuntu 12.04 by default. On modem initialization it sets text mode instead of PDU mode for SMS, but newer modems can't work in this mode. I understand the GUI works well and has been introduced into Saucy Salamander and later versions, but Modem Manager versions 0.6 or later has not yet been made available for 12.04 LTS users which enables its SMS functions etc to work. It is hoped that an updated version of Modem Manager that addresses this and other bug fixes can be introduced into 12.04 LTS very soon for users like myself who have been looking out patiently for a couple of years for this functionality. Thanks in advance for the anticipated support... cheers!
