I was able to install Debian Buster with LXDE on a Toshiba Satellite C660D-15D and could even get the wireless working after enabling the non-free repository.
But I got stuck on the screen resolution. So far I am unable to use the often recommended xrandr tool to add the resolution I need. The command doesn't seem to be even availabe when using LXDE. But I discovered that instead lxrandr is present. But this seems to be a graphical tool that just starts the GUI tool which doesn't allow me to add the native screen resolution of the device (1366 x 768) instead of 1024 x 768.
What do I get wrong here?

Re: Screen resolution on Toshiba Satellite C660D-15D
What is the graphics hardware & driver? Does it need non-free firmware?
The xrandr command is provided by the x11-server-utils package:

Re: Screen resolution on Toshiba Satellite C660D-15D
Thank you for your quick answer.
The non-free repository was at least necessary for the wireless. (But so far every second boot the wireless is missing again. I don't know what to make of this. Maybe my configuration is less than ideal in that aspect too. During the initial setup Debians installer told me that the missing firmware was: "rtlwifi/rtl8192cfw.bin". This is why I added the non-free repository.)

Re: Screen resolution on Toshiba Satellite C660D-15D
Use the -k switch for lspci(8) to show the status of the kernel drivers. Have you installed the firmware-amd-graphics package? As per the Debian wiki AMD page.

I found a download page for the card lspci has identified: GNU/Linux driver for my card but there is a remark stating: "Automated installer and Display Drivers for Xorg 6.9 to Xserver 1.12 and Kernel version up to 3.4". And to my knowledge Buster uses kernel 4.19. So it doesn't seem to be what I need. Or do I get that wrong?

The lines we want are beneath that one so either modify your grep command or view the output without it.Onsemeliot wrote:Code: Select all

If you actually post what you tried along with any error messages then we could probably help you with that.Onsemeliot wrote:I only (unsuccessfully) tried using the xrandr command to add the resolution manually.
Good grief, no. The proprietary AMD drivers are only intended for their PRO series video cards and they're tricky to get working with Debian anyway.Onsemeliot wrote:I'm not sure what exactly you are referring to with "Debian wiki AMD page". Is this the guide you mean?
The page I meant comes up as the first result if you enter "Debian wiki AMD" into a search engine: https://wiki.debian.org/AtiHowTo
And I ask again:
^ That will probably fix things. We've had about 2.7 million threads on these boards about this exact same subject, strange that you didn't find any of them when you searched before starting this thread...I wrote:Have you installed the firmware-amd-graphics package?

Re: Screen resolution on Toshiba Satellite C660D-15D
Sorry, I seemingly didn't try hard enough to find what I was needing. I guess I shouldn't have used the laptop model name in my search but the name of the graphics card I eventually found using lspci. I suspect this is partially because I wasn't sure if this was actually the name of the hardware or just of the (probably wrong) drivers used. I obviously still miss basic knowledge.
Concerning the "firmware-amd-graphics" package I made the wrong assumption. I didn't understand that this was the actual name of the package I should install and I thought you meant just the proprietary AMD drivers for my hardware that can be downloaded from the AMD web page. But I installed it now and it instantly worked.
Thank you very much for your patience.
