Hello, I have been using this Thinkpad T520 for 1.5 years with Qubes R2, R3.0 and now R3.2 without major hardware issues (not tested with R3.1). Well, I had a problem with Intel gfx and R3.2, but it's fixed now (details somewhere below).
Long story short: it works. CPU: i5-2520M 2.50GHz VT-x: works VT-d: works SLAT/EPT: supported TPM: present, not tested RAM: it had only 4 GB in factory configuration, documentation says it supports max 8 GB, but in fact it supports up to 16 GB of RAM (2*8). GPU: integrated Intel HD Graphics 3000, works, but: Under R3.2, i915.enable_rc6=0 needs to be added to kernel parameters to prevent random reboots when external monitor is connected, as described there: https://groups.google.com/d/msg/qubes-users/DSFcUer3C7M/Rbno0VdfBQAJ Suspend/resume: works. Sound: works Microphone: works Ethernet: Intel 82579LM Gigabit, works Wi-Fi: Intel Centrino Ultimate-N 6300, works Card reader: Ricoh PCIe SDXC/MMC Controller, works Firewire: Ricoh R5C832 PCIe IEEE 1394 Controller, works Display: TFT 15.6" 1600x900, anti-glare Docking station: tested with Lenovo 4338, works Bluetooth: BCM2045B, detected as USB device, but not tested Camera: not present Fingerprint reader: not present Keyboard, trackpoint and touchpad: work There are additional function keys, most of them work, at least these used by me: volume control, mute, LCD dim and keyboard light. ExpressCard/34 port: works, but without hotplugging, as it is not supported by Qubes anymore: https://groups.google.com/d/msg/qubes-users/JVOpOrOPvZk/5Xar5LS8BwAJ USB: two USB 2.0 controllers. One with 2 ports and all internal devices (bluetooth, docking station and its USB ports), and second with just 2 ports. Controllers have shared RMRRs, but they can be assigned to different appVMs if these VMs have pci_strictreset=false. Note: since upgrade to R3.2 I'm no longer able to assign USB controller to Win7 HVM. For USB 3.0 I use ExpressCard adapter (on Renesas uPD720202 chipset) and it works well. AFAIR I had to disable power management for pccard in BIOS. All communication ports or devices can be disabled in BIOS: network cards, bluetooth, modem, USB ports, firewire, ExpressCard slot, eSATA port, ultrabay (CD/HDD), card reader, camera, microphone and fingerprint reader. Some of these ports/devices are not present in this model of T520. There is also the physical switch for disabling bluetooth and Wi-Fi, it also works. -- yaqu -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
