Howdy, I am blind, and don't even have a screen connected to this computer. For some reason, my console size is 30 lines and 80 columns. I've not seen this small of a console before. they usually have 50+ lines and over 100 columns. I have searched for quite a while, but not found anything about increasing the console size. I did find a python script that will set the screen to the actual size, but it returns 30 80 as well, so no luck there either. One site said you could just export the lines and columns you want, but that failed, even though the variables were set correctly. Is there any way to set the lines and columns regardless of the size your computer believes the screen to be? Thanks for any help, Storm -- Powered by Arch Linux!

Storm- Is this on a braille display via brltty? Or via a screen reader/TTS/speech synthesizer? If the former, which model is your braille device? I have noticed this issue before with VGA framebuffer resolutions (or KMS mode resolution) being less than ideal, but I'm not quite sure if brltty does translations *from* the VGA or if it occurs at a lower level and emulates a VGA display to the kernel. I unfortunately have no experience with this or frame of reference and no devices to test with either, but I'd say I'm intrigued by how it handles this. If brltty does appear as a VGA device to the kernel, I should note that 80x30 is a standard mode of grub legacy (specifically, mode 0f05 or type 4). However, unless you specifically installed and configured your system to use grub legacy, I can't see that being relevant. I would try setting: GRUB_GFXMODE=1024x768x24 # or whatever the max resolution is? # start conservatively and work your way up GRUB_GFXPAYLOAD_LINUX=keep in /etc/default/grub and re-running grub-mkconfig -o /boot/grub/grub.cfg to see if this makes any difference either way in how it renders to however you're interacting with it. Best of luck; do please keep us posted, as I've never interacted with vision-impaired terminals before so this is new territory for me. -- brent saner http://www.square-r00t.net

Howdy, I am using speech and screen. My screen reader is Fenrir, available from the AUR: https://github.com/chrys87/fenrir I am using an Odroid XU4 with which is an ARM machine. So it uses uboot. I did uncomment a larger screen setting in the boot.txt file and did mkscr to compile it. Here is the line from boot.txt: # 1920x1080 (1080P) without monitor data using generic information (1080p-noedid) setenv videoconfig "drm_kms_helper.edid_firmware=edid/1920x1080.bin" It still insists on the tiny terminal though. This is the only thing standing between me and the perfect setup lol. Thanks Storm On Sun, Aug 27, 2017 at 10:50:29AM -0400, brent s. wrote:

You are using Arch Linux ARM, which is a separate distribution and you want to ask on their support channels. This mailing list is for Arch Linux which supports only x86-64 (and i686 for a little while longer) and uses different methods to boot (different bootloaders or by using EFISTUB on UEFI systems) so I suspect not many people here will know how to make uboot do what you want. -- Mauro Santos

I'd suggest trying to use "stty rows N columns M" to force terminal size regarless of what the kernel believes it to be. Jerome -- mailto:jeberger@free.fr http://jeberger.free.fr Diaspora*: https://framasphere.org/u/jeberger

Howdy, The stty command did chage the variables, even reported by tput, but the actual size did not change. Thanks Storm On Sun, Aug 27, 2017 at 06:35:30PM +0200, Jérôme M. Berger wrote:

I thought that was rows and cols for the variable names to do this, but could be wrong. On Sun, 27 Aug 2017, Storm Dragon via arch-general wrote:
