The SD card reader on my new L530 is not working.
Please let me know what diagnostics I can provide to help fix this.
I have a package to supply this driver, in ppa:jamesf/lenovofixes.
The package is source for a kernel module to enable the hardware. It is in DKMS format. This package includes a udev rule to make automounting work properly.
(I have been working on enabling these Lenovo systems for Canonical/Lenovo. The driver source for this is not formally released by Realtek and can't yet be used upstream, and so unfortunately it's not going to find its way into the upstream Linux kernel or Ubuntu kernels in the near future. In the meantime, there's this.)
While you're at it, you may want to try the micmute package from that ppa - if your mic mute hard button is misbehaving.
Here's the English translation of Christian's solution: http://ubuntuforums.org/showthread.php?t=2059763&highlight=l530+sd+card
it's a 'Realtek Semiconductor Co., Ltd. RTS5229 PCI Express Card'
its german language but i think you'll get the point.
kind regards Christian Zudeick
