I have been reading about webcams, etc. and Linux and am working with my LePotato running Ubuntu 22.04. I added the Arduino CSI-USB converter so I can plug in an RPiHQ cam into the USB port. I see the following in the log messages: pi@lepotato:~$ dmesg | grep Camera [ 4.431905] usb 1-1.2: Product: Arducam IMX477 HQ Camera [ 8.798501] uvcvideo: Found UVC 1.00 device Arducam IMX477 HQ Camera (0c45:636d) [ 8.806595] input: Arducam IMX477 HQ Camera: Arduc as /devices/platform/soc/d0078080.usb/c9000000.usb/xhci-hcd.2.auto/usb1/1-1/1-1.2/1-1.2:1.0/input/input3 But I have no idea how to test further. I've tried cheese: cheese ** (cheese:4159): ERROR **: 13:06:46.007: cheese-application.vala:89: Unable to initialize libcheese-gtk Trace/breakpoint trap (core dumped) cheese -d [total guess at device] same as above And libcam-hello: libcam-hello -bash: libcam-hello: command not found I've tried installing libcam following what I found Googling, but I just keep digging a deeper hole. I am lost. The camera works fine with Raspbian Bullseye in CSI mode, but my limited knowledge doesn't tell me whether the messages I'm seeing with Armbian mean much. What should I do next? Thanks.

Hello, I've Googled for a solution without success. Today, I set up a Le Potato w/Armbian XFCE 22.04. All was well except only root had RDP access. After trying various ideas from the internet, I still can't get in as a normal user. After the last attempt, I see this in /var/log/xrdp.log: [20220830-08:06:43] [INFO ] Socket 12: AF_INET6 connection received from ::ffff:192.168.50.226 port 63884 [20220830-08:06:43] [INFO ] Using default X.509 certificate: /etc/xrdp/cert.pem [20220830-08:06:43] [INFO ] Using default X.509 key file: /etc/xrdp/key.pem [20220830-08:06:43] [ERROR] SSL_read: I/O error [20220830-08:06:43] [ERROR] libxrdp_force_read: header read error [20220830-08:06:43] [ERROR] Processing [ITU-T T.125] Connect-Initial failed [20220830-08:06:43] [ERROR] [MCS Connection Sequence] receive connection request failed [20220830-08:06:43] [ERROR] xrdp_sec_incoming: xrdp_mcs_incoming failed [20220830-08:06:43] [ERROR] xrdp_rdp_incoming: xrdp_sec_incoming failed [20220830-08:06:43] [ERROR] xrdp_process_main_loop: libxrdp_process_incoming failed [20220830-08:06:43] [ERROR] xrdp_iso_send: trans_write_copy_s failed [20220830-08:06:43] [ERROR] Sending [ITU T.125] DisconnectProviderUltimatum failed [20220830-08:06:43] [INFO ] Socket 12: AF_INET6 connection received from ::ffff:192.168.50.226 port 63885 [20220830-08:06:43] [INFO ] Using default X.509 certificate: /etc/xrdp/cert.pem [20220830-08:06:43] [INFO ] Using default X.509 key file: /etc/xrdp/key.pem [20220830-08:06:43] [INFO ] Connected client computer name: YOGAS1 [20220830-08:06:43] [WARN ] Received [MS-RDPBCGR] TS_UD_HEADER type 0xc006 is unknown (ignored) [20220830-08:06:43] [WARN ] Received [MS-RDPBCGR] TS_UD_HEADER type 0xc00a is unknown (ignored) [20220830-08:06:43] [INFO ] xrdp_load_keyboard_layout: Keyboard information sent by the RDP client, keyboard_type:[0x04], keyboard_subtype:[0x00], keylayout:[0x00000409] [20220830-08:06:43] [INFO ] xrdp_load_keyboard_layout: model [] variant [] layout [us] options [] [20220830-08:06:43] [INFO ] TLS connection established from ::ffff:192.168.50.226 port 63885: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 [20220830-08:06:43] [INFO ] xrdp_caps_process_pointer: client supports new(color) cursor [20220830-08:06:43] [INFO ] xrdp_process_offscreen_bmpcache: support level 1 cache size 10485760 MB cache entries 100 [20220830-08:06:43] [INFO ] xrdp_caps_process_codecs: nscodec, codec id 1, properties len 3 [20220830-08:06:43] [WARN ] xrdp_caps_process_codecs: unknown codec id 5 [20220830-08:06:43] [INFO ] xrdp_caps_process_codecs: RemoteFX, codec id 3, properties len 49 [20220830-08:06:43] [INFO ] Loading keymap file /etc/xrdp/km-00000409.ini [20220830-08:06:43] [WARN ] local keymap file for 0x00000409 found and doesn't match built in keymap, using local keymap file [20220830-08:06:43] [INFO ] loaded module 'libxup.so' ok, interface size 10296, version 4 [20220830-08:06:43] [INFO ] started connecting [20220830-08:06:43] [INFO ] lib_mod_connect: connecting via TCP socket Basically, I get a black screen. For grins, I looked up how to enable RDP on my Raspberry Pi 4 running Raspbian Bullseye - basically do an apt-get install xrdp and done. Sure enough, I did that and sure enough, I am able to RDP into my Pi no problem. So, what am I missing??? Thx. Khobar
